The IdeaCentre Flex 20 is another innovative desktop PC/tablet hybrid from Lenovo. It looks just like a standard all-in-one desktop PC, but fold up the stand and unplug the power cord, and you've got a 20-inch tablet.
The Dell XPS 8700 Special Edition tries to provide you with lots of performance power, some added connectivity features, but it doesn't leave much room for future expansion or a second graphics card. It delivers in the performance category, but it's pricier than most other desktops.
The HP Envy 700-030qe is a member of the class of systems that used to be called high-end multimedia desktop PCs. The fact that you can get all that power for over a $1,000 less than you used to is amazing.
The Lenovo IdeaCentre Horizon is a 27-inch all-in-one and tablet PC hybrid. It has an Intel Core i7 CPU, 8GB of RAM and a multi-touch 1080p display. Performance with this hybrid is good and it comes pre-loaded with fun, useful software.
The Acer Aspire A5600U-UB13 is a nice looking all-in-one desktop PC with a solid feature set and acceptable, though not exceptional performance. It's a decent all-in-one desktop at a decent price, but there are better systems out there for not much more money.
The Dell XPS 18 is a portable all-in-one desktop PC. Larger than a tablet or laptop, but smaller than a full blown all-in-one desktop, the Dell XPS 18 lets you bring a full Windows 8 PC around the house or office corridors with you. It mostly works, though the market for such a product is still in its beginning stages.
