If you're looking for a laptop for just Web and Word Processing, consider looking in the local classifieds or even ebay. You can get an older "3 to 5" year old laptop, for next to nothing.
I picked up a Dell Inspiron 3200 with P3 733Mhz, 256MB ram, 4GiG HDD & 13.3" screen . I formatted the HDD, Installed Windows XP PRO, Installed just the needed drivers, added a wireless Network adapter...
It sits on my breakfast counter and I surf the web while eating breakfast. I also have Office XP installed on it. That's all I use it for.
It's also networked to my other PC's.
I bought it for $50 USD with the case (bag).
