downsides, that I think I notice

2.33 GHz processer? My 4 year old laptop has more than that.
12GB of system memory, if it is RAM, then that is amazing, but it is is hard drive, it is horrible.
It runs on XP, most computers run on Vista now, and if you go the HP, or some other brand, they don't even stock XP systems anymore.
Not sure if that is really some of the downsides, but that was what popped out at me when I looked at the Tech Specs page of it.
