Lenovo IdeaCentre Horizon 27 ( Core i5)
Tabletop PCs may not be fully ready for the mainstream, but this coffee-table-size version from Lenovo is fun to use, and doubles as a solid all-in-one desktop.
Dell XPS 18
It's the best of the small handful of current tablet/all-in-one hybrids, with a subtle, sophisticated design and good battery life, but this new genre is still in its early days.
Pricing not available
Asus Transformer AIO
You'd be smart to wait and see how the market develops, but Asus has used the freedom of the still-forming all-in-one/tablet hybrid category to create a compelling Windows 8/Android device in the Transformer AIO.
Digital Storm Bolt
By sacrificing luxuries, the performance-focused Digital Storm Bolt will satisfy most PC gamers for significantly less than most other small gaming desktops.
Samsung Series 7 700A3D
The Samsung Series 7 isn't the fastest, or the most fully featured midrange all-in-one, but casual PC users should consider it for its affordability and overall polish.
Dell Inspiron One 2330
Dell's workmanlike Inspiron One 2330 won't change your life, but it will meet all of your basic mainstream desktop needs while also providing a few useful extras.
Look no further than the Toshiba LX835-D3380 if you want a comfortable, speedy all-in-one on which to learn Windows 8.
Apple iMac ( 21.5-inch, 2.7GHz, fall 2012)
The 21.5-inch iMac will be a compelling lower-cost all-in-one for Mac loyalists, but you can get more capabilities from similarly priced Windows all-in-ones.
Maingear Potenza Super Stock ( Core i5 3.1 GHz)
Accept the limitations of its scaled-down chassis, and the Maingear Potenza Super Stock will provide top-notch gaming horsepower in an attractive package.
Asus ET2300INTI All-in-one PC
It's not the most attractive PC out there, but the Asus ET2300INTI has a broad array of features that will entice those looking for a mainstream Windows 8 all-in-one.
