I have the 9 Acer Aspire One from Best Buy. The model has an Atom processor with 1G RAM and 8G SSD with Windows XP. The 8G SSD definitely poses challenges with the write function being so slow on XP machines. The system is extremely sluggish when surfing the web using IE. I made some minor setting changes to see if that would speed things up to no avail. I tried other browsers as well. I tried Opera, Firefox, old Netscape, and Safari for Windows. None of these made a huge difference. I did try Chrome and saw impressive results. Chrome lets me fly on the Internet. I did some comparisons on the same machine between IE and Chrome and I could get to sites about 2-3 times faster on average. Chrome would bring up msnbc.com in about 3 seconds. IE required a painful 7 seconds. I'd recommend installing and using Google's Chrome as your default browser. IE is a complete hog. Mozilla and Opera are not bad, but Chrome seems to be the best for speed on my machine.
