Moving into an Apple-centric dorm that's brimming with Macs, iPads, and iPhones? The $99 Apple TV will be a perfect gift. It's the only streaming box that can handle Netflix and iTunes, and AirPlay lets you send content from any other iOS device wirelessly.
Don't fret that the Klipsch Image S4 headphones are a few years old -- they're still one of the best deals out there, and a perfect gift for anyone with a phone or music player. The S4i, which can also be had for less than $100, integrates an inline remote and built-in microphone for iPhone calls. For Android smartphone users, Klipsch also makes the S4a. (Looking for more?

Logitech's Wireless Solar Keyboard K760 can stay charged from indoor light sources, and easily toggle between up to three Bluetooth devices (Mac, iPhone, iPad). It's the perfect keyboard for Apple multitaskers. (Just looking for an iPad keyboard? Check out the $100 Ultrathin Keyboard Cover or the $130 Solar Keyboard Folio, also from Logitech.)
Yeah, it's not as cool as an iPod Touch or an iPhone, but the Nintendo DSi -- now just $99 -- is as durable as a tank, has a battery that lasts forever, and is still the only portable system where you can play Mario, Zelda, and Pokemon. (Supersize to the DSi XL for $30 more, or step up to the 3DS for $70 more).
The Roku HD is, hands-down, the best media streamer you can buy for under $60. It delivers Netflix, Hulu Plus, Amazon Instant, Pandora, Crackle, and literally hundreds of other online video and audio channels. If you can live without iTunes and YouTube, this one is a no-brainer. (Note: The nearly identical Roku LT is available for $10 less, but it's nearly always out of stock.)
There are a glut of Bluetooth speakers with rechargeable batteries out there, but the $99 Soundfreaq Sound Kick strikes a strong balance between size, sound quality, and price. Use it to stream music from any smartphone or iPad.
