I'm glad you love your macbook, but would a similar-enough computer _really_ not do it for you? When I upgraded from a netbook as my main machine to my Toshiba Z830, it was amazing, but then again, that is comparing a $200 machine to a $700 machine.

I can't really see that same $500 difference in price making something like the $1200 MBP so much better than what I've got, with marginal utility and all that going.

I don't by any means think that getting a high end machine is a bad idea, but I do think that once you get something that is a high quality item, you definitely reach the "good enough for me" stage.
