I am selling my old laptop. It is an Acer Aspire 5630-6228. Purchased 2 years ago for around $800, and I have upgraded the memory to 4gb and the OS to windows 7 professional.
Specs:
Intel Core2 duo T5500 1.66ghz. (alot faster than the Intel dual core processor, Celeron dual cores, or the Athlon 64 x2)
4gb of DDR2 RAM
160GB HDD
15.4 WXGA CrystalBrite screen
DVD±RW (±R) Combo drive
5 in 1 card reader
1.3megapixal web cam
Windows 7 professional
$350 and price is pretty firm.
Looks like this, I get actual pictures up when I find my digital camera.
