The asterisks symbolize hardware that comes stock with the tablet PC; everything else is basically unknown to me.

I figure I can always just buy as cheaply as possible from the site, and then sell off parts to purchase higher-grade parts to upgrade; would this be possible, or more correctly, worth it? I've never used a 64-bit OS.

Also, I have a dedicated laptop which I use as a desktop, and two netbooks; would this purchase make this tablet purchase redundant?

My laptop is an HP DV9000 CTO running Windows Vista Ultimate 32-bit, which I paid about $1000 for four years ago for college.

My netbooks are a white Samsung NC120 with 2GB memory running Windows 7 Ultimate, and a blue Samsung NC10 running Windows Vista Ultimate (The only disks the university provides are the highest versions). I paid $308 shipped for the blue Samsung, and $300 for the white one, upgrading the memory afterwards.

I primarily use the computers for writing for my English major, related classes, and pleasure.

If anyone would care to explain the unmarked items' differences to me, and help me make an intelligent purchase, I would appreciate it Thanks in advance.
