Can someone tell me here if this is a huge deal i will be using my system for work and games and stuff.. and quite often hooking it up to a bigger monitor... but is there a big difference here. I like the portability but is the 15inch going to be ok... or is it really that bad... just want some opinions on the differences i do still see a ton of good systems with the 15inch.....with SXGA+ oh well let me know..
