In this first run of Windows 8 devices, manufacturers are essentially throwing things against the wall to see what sticks. We've seen every size, every form factor, every direction and angle of rotation — companies are trying desperately to figure out the best way to take advantage of everything Windows 8 can do.

Even Lenovo's lineup is all over the place. There's the Lynx convertible, which transforms from laptop to tablet. The Twist rotates and folds, and looks like the X Series tablets we've seen for years. And then there's the IdeaPad Yoga, perhaps the most enticing of the bunch — we've been waiting for this device to come out ever since it was announced at CES back in January. The Yoga's crazy gimmick is its hinge, which allows the screen to fold all the way back over the keyboard, so you can hold your laptop like a tablet.

Carnival sideshow tricks aside, though, the IdeaPad is still a pretty appealing Windows 8 laptop. My review unit has a 1.7GHz Core i5 processor, 4GB of RAM, and a 128GB SSD in an attractive 3.5-pound package. It's more laptop than tablet, but it's trying to be both — and much more. Is this the Windows 8 ultrabook for you (and for me)?
