I guess I will wait to see the pricing on the XPS M1210...I am guessing it'd be pretty expensive.
I know you can get the basic 710m for a little over $1000, but I was going to get one with a warranty that would at least have some kind of at-home service instead of mail-in service.
My brother recently got an Inspiron that didn't start up when he received it and he had to send it back, it took awhile, and it turned out to be a bad motherboard. So I am a little wary.
I used to have an IBM and I didn't think it was as good as my Dell, though.
