But every time I wanted to change songs, I had to go to another room and make a few mouse clicks on my computer. Ever since then, I’ve been waiting for someone to come up with a good, affordable remote control that lets me change tunes no matter where I am in the house.

It turns out, I already owned that device. It’s an iPod touch. A new program released by Apple in July was all it took to convert my MP3 player into a sophisticated remote control for my digital-music collection. That program, called simply Remote, runs on the iPhone as well as on the iPod touch, a version of the Apple MP3 player that has an iPhone-like touch-sensing screen and Internet-access capabilities using Wi-Fi wireless technology. Remote is available free of charge on the online App Store that Apple has used since July to distribute software for those devices.

In essence, Remote is a remote control for all music stored on a Mac or Windows PC that’s loaded into iTunes, Apple’s music jukebox software. It allows you to jump between playlists, browse artists and pump up the volume. For the program to work, you need to buy into using other Apple entertainment products.

In the simplest setup, Remote lets you control the music from stereo speakers connected directly to a PC. But it’s most useful when you use a PC to deliver audio to additional speakers around a home — say, a pair on the patio and in the living room.

Apple sells a couple of products that receive audio signals from a PC running iTunes. Both work wirelessly over a Wi-Fi home network so you don’t need to put holes into your walls to run computer and speaker wires. I tested Remote using both. One is an Apple TV, a $229 set-top box in my living room that plays digital audio and video through a standard home-theater system. The other is an AirPort Express, a $99 Apple wireless networking device on my patio connected to a pair of powered A5 speakers made by Audioengine, of San Jose, Calif. A third set of speakers was connected to an iMac in the kitchen, where I store all of my digital music. (The least expensive iPod touch costs $299.)

It was a breeze to configure the Apple TV and AirPort Express to show up as remote speakers in iTunes on my computer. Setting up Remote to give me mobile control over this array of speakers was trickier. After installing the program on my iPod touch, I couldn’t get it to work with iTunes on my PC. After 20 minutes of fiddling with the security settings for my Wi-Fi base station, iTunes finally recognized Remote. I was in business.

We all know how confusing the remote controls for TV sets and stereo systems can be. Remote, by contast, cleanly displays all the music on my PC on the color screen of my iPod touch.

The program let me flip through artists, albums and playlists with simple finger swipes. But I was sorry that Remote doesn’t have a feature in the iPod touch called cover flow that lets users browse their music libraries by flipping through album-cover art. Apple says it may offer the feature in the future.

The software also let me easily turn on and off the music from my speakers in my kitchen, living room and patio. I could have all the speakers on at once — good for a party. The sound was terrific. The crisp-sounding $349 Audioengine speakers don’t require a stereo receiver.

Because Remote uses Wi-Fi to communicate with iTunes, I could control music anywhere around my house and backyard, which are small enough to be fully covered with a signal from my Wi-Fi base station. That’s a big plus over conventional remote controls that use infrared, a technology that doesn’t work through walls.

One drawback: The battery in my iPod touch drained overnight when I configured the device to stay connected to iTunes, a feature that increases software responsiveness. Changing the setting let me go days without recharging my iPod touch, but it meant I had to wait a couple of seconds for Remote to connect to iTunes when I started up the software — an acceptable trade-off.

Another multiroom audio product with a good remote control is the ZonePlayer from Sonos, an equipment maker based in Santa Barbara, Calif. That system has some advantages over Apple’s offerings, including the ability to access tunes from online music services, such as Pandora and Rhapsody, and separate volume controls for each set of speakers.

The Sonos system starts at $999 for a remote control and wireless receivers, without speakers, that can deliver music to two rooms.

For people who already own an iPod touch or iPhone, Remote is a good reason to buy an AirPort Express, and fill your home with music.

iPod is a brand of portable media players designed and marketed by Apple Inc. and launched on October 23, 2001. The product line-up includes the hard drive-based iPod Classic, the touchscreen iPod Touch, the video-capable iPod Nano, and the compact iPod Shuffle. The iPhone can function as an iPod but is generally treated as a separate product. Former iPod models include the iPod Mini and the spin-off iPod Photo (since reintegrated into the main iPod Classic line). iPod Classic models store media on an internal hard drive, while all other models use flash memory to enable their smaller size (the discontinued Mini used a Microdrive miniature hard drive). As with many other digital music players, iPods can also serve as external data storage devices. Storage capacity varies by model.

Apple’s iTunes software can be used to transfer music to the devices from computers using certain versions of Apple Macintosh and Microsoft Windows operating systems. For users who choose not to use Apple’s software or whose computers cannot run iTunes software, several open source alternatives to iTunes are also available. iTunes and its alternatives may also transfer photos, videos, games, contact information, e-mail settings, Web bookmarks, and calendars to iPod models supporting those features. As of September 2008, more than 173,000,000 iPods had been sold worldwide, making it the best-selling digital audio player series in history.

The iPod line came from Apple’s “digital hub” category, when the company began creating software for the growing market of personal digital devices. Digital cameras, camcorders and organizers had well-established mainstream markets, but the company found existing digital music players “big and clunky or small and useless” with user interfaces that were “unbelievably awful,” so Apple decided to develop its own. As ordered by CEO Steve Jobs, Apple’s hardware engineering Chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Jonathan Ive. The product was developed in less than one year and unveiled on 23 October 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put “1,000 songs in your pocket.”

Apple did not develop the iPod software entirely in-house, instead using PortalPlayer’s reference platform based on 2 ARM cores. The platform had rudimentary software running on a commercial microkernel embedded operating system. PortalPlayer had previously been working on an IBM-branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface under the direct supervision of Steve Jobs. As development progressed, Apple continued to refine the software’s look and feel. Starting with the iPod Mini, the Chicago font was replaced with Espy Sans. Later iPods switched fonts again to Podium Sans—a font similar to Apple’s corporate font, Myriad. iPods with color displays then adopted some Mac OS X themes like Aqua progress bars, and brushed metal meant to evoke a combination lock. In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).

In September 2007, during the course of a lawsuit with patent holding company Burst.com, Apple drew attention to a patent for a similar device that was developed in 1979. Kane Kramer patented the idea of a “plastic music box” in 1979, which he called the IXI. He was unable to secure funding to renew the US$ 120,000 worldwide patent, so it lapsed and Kramer never profited from his idea. Kramer is now in talks with the company to discuss how he will be reimbursed.
iPods have won several awards ranging from engineering excellence, to most innovative audio product, to fourth best computer product of 2006. iPods often receive favorable reviews; scoring on looks, clean design, and ease of use. PC World says that iPod line has “altered the landscape for portable audio players”. Several industries are modifying their products to work better with both the iPod line and the AAC audio format. Examples include CD copy-protection schemes, and mobile phones, such as phones from Sony Ericsson and Nokia, which play AAC files rather than WMA.

In addition to its reputation as a respected entertainment device, iPods have also become accepted as business devices. Government departments, major institutions and international organizations have turned to the iPod line as a delivery mechanism for business communication and training, such as the Royal and Western Infirmaries in Glasgow, Scotland where iPods are used to train new staff.

iPods have also gained popularity for use in education. Apple offers more information on educational uses for iPods on their website, including a collection of lesson plans. There has also been academic research done in this area in nursing education and more general K-16 education. Duke University provided iPods to all incoming freshmen in the fall of 2004, and the iPod program continues today with modifications.
