In our laptop tests, our W510-1422 configuration's battery life was stellar at nearly 14 hours, 39 minutes; however, performance was strictly tablet. The W510-1422's dual-core Intel Atom Z2760, 2GB of DDR memory, and 64GB SSD combined for a 17 on PCWorld's WorldBench 8 test suite--way below par for laptops.
In our tablet tests, the system fared far better. Performance was on par with its Atom-based peers, though battery life dropped to only about 8 hours in our continual video rundown test. Subjectively, the W510-1422 unit feels nimble enough, and 1080p video played fine in the Windows 8 video player. The popular VLC player had issues using its own internal codecs, so if that's your preferred player, you'll need to set it to use the system codecs.
The W5's widescreen display will appeal to some, but kill the deal for others--a major conundrum for those eyeing the Surface and other Windows 8 tablets as well. In the end, eying those others might be a good idea--the W510 is a decent product, but it's not great and there's a lot of competition.
