I'm looking for a good deal on a lightweight (preferable < 4 lbs) laptop. I'll use it mostly for word processing, internet, etc.. A 7" screen is too small though. The keyboard should be comfortable for typing for long periods. I don't want Windows Vista because some of the software I have (Endnote, Dragon Naturally Speaking) is not compatible with Vista. I have an extra licensed copy of Windows XP. If the computer comes with Vista can I just change it back to XP myself? Also I would like it to have an internal CD/DVD read/writer and at least 1MB RAM. Most of the deals I see out there are for laptops that weigh around 6 pounds. A tablet would be okay too, if it is not too expensive. Most of the ones I see are >$850 and I was hoping to find something closer to $500. Is that realistic? If anyone sees a deal that meets my criteria please let me know.
