For an extra $50, Asus offers a configuration with a 64GB SSD instead of a 32GB one. If you're planning to store a decent amount of apps, or frankly, any HD video content, it's a worthwhile upgrade.
The 1.3GHz Intel Atom Z3740 CPU is par for the course with similar systems, and it won't surprise you to see that they all performed reasonably closely in our benchmark tests, although the VivoTab 8 wasn't the top performer in any individual test.
For an 8-inch experience, an Atom CPU should be fine, and the tile-based Windows 8 interface and apps optimized for it work especially well. Drop back to the traditional desktop, and some programs may feel a bit sluggish, but on such a small device your expectations are in line with that.
The Acer W4 is the king of battery life in the 8-inch arena, with a duration we clocked at 8:36, but the VivoTab 8 is a strong second, running for 7:39 on our video-playback battery drain test. The best laptops and tablets (especially OS X and iOS devices) run longer, but seven to eight hours for a handheld device running a full version of Windows 8 should be more than enough for most scenarios.
Eight-inch Windows 8 tablets are finding their own in their second or third revisions, with decent battery, solid performance, and a fairly uniform set of designs and features. Of the current crop, the Lenovo ThinkPad 8 costs more but has a great design and high screen resolution, and the Acer W4 has the longest battery life.
The Asus VivoTab 8 could use a thinner body and more ports, but it includes a Wacom stylus. If that's a feature you think you'll really need, you can probably look past its other shortcomings.
