Not a genius, just a techie (both for work and leisure), but it is a decent deal. However, there is only 1GB of RAM, and with Vista this is simply not enough. It would make the computer pretty slow, even if you only do simple stuff like web browsing, office work, ... It should be possible to upgrade this to 2GB (30-40$ for the part), however, if you can't do it yourself, the cost will be too much and it would be better just to get a model with 2GB integrated, like the Toshiba at 550$ at
Best Buy. Would love to tell you to go ahead, but I would not for my friends and family, so I want you to not be disappointed.
Basically, check the total memory, min 2GB. If you want to do light stuff, most CPUs are OK. The rest is standard on all models: basic wireless, wired network, most still have a modem. Some people hate some brands, however on the lower price models, I haven't seen any big differences. The Acers seem a bit cheap, so at the same price I'd choose another brand, but it is a matter of personal preference!
