Has anyone ever owned or used an All in One computer? I have heard negative things about them in the past, but wondered if they might have gotten better.

I have a Best Buy gift card (to be used on a computer) and since I can't find a laptop that fits my needs (plus I have a fairly new laptop already) so I was looking at an AiO instead. This one in particular: http://www.bestbuy.com/site/asus-zen...uctCategoryId=

Any insight or advice?
