- Sony Ericsson Equinox TM717 - carbon black (T-Mobile)
- Photo gallery:Sony Ericsson Equinox TM717The Sony Ericsson Equinox is the first phone from the manufacturer to land at T-Mobile since the TM506. In many ways the Equinox is a fitting successor; like the TM506 it has a thin flip phone design and it sports a similar feature set that includes...

- Sony Vaio X (VPC-X115KX/N Signature Collection, gold)
- Sony has thus far taken a position just adjacent to Apple's when it comes to the question of Netbooks. Rather than embracing these low-cost, low-power systems that have become incredibly popular with bargain-hunting consumers, Sony stayed out of the market initially. Its subsequent entries have skirted the outer edges of...

- Toshiba Satellite L455-S5975
- We've said it before, and we'll say it again: especially in this economy, it's hard to hate a laptop that only costs $350. It's even harder to hate a Windows 7 laptop that costs that much. The Toshiba L455-S5975 is, by 50 dollars, the least expensive notebook computer in our...

- Averatec D1130 All-in-One
- The Averatec D1130 All-In-One is a stripped-down version of the D1133 we reviewed last month, and while this version cuts the price down to only $399, it also strips away many of the features that gave the higher-end model some value. With its puny 1.6GHz Intel Atom chip, 1GB of...

- Acer Aspire Revo AR1600-U910H
- Typically our challenges with the emergent Nettop category have been that real budget PCs cost just a little bit more and provide a dramatic performance uptick, and similarly priced Netbooks offer equivalent performance with the added benefit of portability. The Aspire Revo 1600's price tag alone answers those issues. ...

- Onkyo is known for having speaker expertise, even though it's not primarily a speaker company. That's because of Onkyo's success selling home-theater-in-a-box systems HTIBs, which combine a speaker system and an AV receiver in a single box, taking some of the confusion out of putting together your own system.
