Ouch, just checked out that laptop. Am I reading this correctly that it's CPU is only 1.4GHz? I think I might be more likely to take a chance on a refurbished core i5 or i3. If you can find something that's at least dual core and 2.3 or so GHz I'd do it.
I'm running on a 6 year old core2duo 1.83GHz with 2 gbs of ram at the moment and it struggles with higher track count song files, but never has a problem with internet browsing or anything like that. That should absolutely not be a problem unless you're running into web pages with gobs of heavy duty flash animations, etc.
