I've owned the dell m1210 for almost two years now, and I love it. I had previously owned a larger, heavier Inspiron, and wanted a laptop that had the same great warranty as Dell provided, but without the back-crushing weight. The m1210 has proven to be both a workhorse and a light machine, with a comfortable to use keyboard. The screen is a 12.1" widescreen, with crisp graphics. I recommend going with a machine that has the non onboard video card -- it allows for games like Sims 2, Neverwinter Nights 2, and WoW to play in beautiful detail. The case of the machine is rugged, and has survived being thrown into my purse for short trips, and into my bookbag for hours of school and study time.
I went out of my way to get the Dell extended warranty, but the m1210 is so well built that the only thing that's required repair so far has been the little rubber feet on the bottom of the machine.
If you want a small laptop with a dual core processor's power, and a tough build, the m1210 is for you!
