Nice setup. I do have a few suggestions/questions.
1. Is there a reason why you chose windows MCE? Is it worth the cost?
2. As mentioned in other threads, it's cheaper to buy the lowest amount of RAM (256mb) from Dell, then upgrade it to 1+gb yourself through online retail stores like
www.newegg.com. Installation is easy.
3. The wireless 2200 B/G card is pretty crummy. I'm having constant connection problems with my linksys54g and netgear router. The B connection's fine but the G connection's fluctuates alot. I'm still tweaking though..
4. Are you going to use the laptop on battery power often? The lifetime of a 6-cell is pretty bad. Consider buying a spare from Ebay or Dell...
5. If you're going to move the laptop around alot, consider a carrying case. Targus XL and Kensington Contour backpacks work well, though a tad expensive.
6. You ARE using coupons right? =)
That's all I can think of. Good luck!
