If it fits the budget, why not use the X3? It will just last longer. And, while most people like us don't load down our computers, the vast majority of users out there have about 30 items in the system tray. I'm always cleaning up someone's computer that is taking 15 minutes to boot.
If all this is for is web surfing and email, then this is overkill. You'd be better off getting a cheap netbook for about $200. You can use a bigger external monitor and keyboard if you want. Or you can get a cheap oem tower for about $300 on sale. Anything from Dell, Acer, HP, etc would work.
A foundation based on 80+ certified PSU even for an el cheapo number cruncher can't go wrong hehe
Negative on any sort of Netbook - they look cute and portable but once u need an inkling of multi tasking, etc they really show their slack processing power IMO My config is good to go for home/oofice tasks like PPT-PDF conversion, blu ray, light audio/video encoding, etc
Here we see the Atom crawling when pitted against a socket 478 chip and a socket 754 sempron
No reason to let the woman in your life suffer like this lol
