sorry this is another 13 vs 15 thread, but i've been reading and reading the forums and i'm still torn i'm trying to decide between ($1414) 13" base model with 128GB SSD ($1699) 15" base model (cost is w/ student discount) any of you out there who was on the fence between 13 vs 15 regret their purchase at all due to CPU performance, screen size, weight? i'll be using mine for internet, email, Adobe CS4/CS5 for hobby, Quickbooks for personal finances, streaming HULU and i would like to actually use it on my lap and not on a desk. i've had my dell desktop for 8 years... so i'm pretty out of the loop on CD2 vs i5 and such and definitely in need of something new as the dell is excruciatingly slow. a friend who has an older 15" argues with me that i should spend the extra cash to get the latest and greatest specs and also that i would more enjoy the magnificent screen on a 15" than a 13". does his argument have any validity? please share your experience! thanks!
