Hey everyone, Longtime lurker, first time poster. I am an avid mac user, but I have some questions that I hope people with more experience can help with. I currently have a 24" iMac, I have had several iMacs/iBooks before... This is mainly background. Not important. I am going back to school and I need to have a MBP. The model you need is up to you, but it needs to be able to run CS5 design premium, Final Cut Express, and the iWork stuff. 13" is automatically out. This is a question of choice between the 15" i7 and 17" i7. Both would get upgraded ram (8Gigs) and both would have the Hi-Res matte screen. The only difference in the specs are the size. (as far as I know.) I want the i7 for sure, so that I get the "better" video card. I have gone to the apple store and compared both the size and weight and while I don't find the difference in weight to be that big of a hindrance, it's the difference in length (or width, depending on how you look at it.) thats cause for concern. Am I going to find cases, backpacks, bags etc. that fit the 17"? The apple stores in my area don't carry ANY that fit it. I have seen some around online, but... 199.99 for a crumpler bag seems steep... and I don't even like their photo stuff. I am more of a "try before you buy" kinda guy. And apparently I like to rhyme... This thing is going to go with me to school Monday-Thursday. (sometimes weekends too.) Once in a while its going to be in a car with a short walk to the school; sometimes its going to be on my back/seat on a train with a short walk to the school. I am never really going to have to carry it more than three blocks in my bag, and again, the weight isn't the issue... its more of the size. I have read all the "Oh, man this thing is too big" threads, and have come to the conclusion that for some its unwieldily and for some it's just fine. The difference in price is only about 200 bucks, and when you are spending around 2600-3000, whats another 200 to gain some extra screen right? It basically comes down to is the extra screen real-estate worth the extra bump in the dimensions... I'm leaning towards yes, but all my comparisons have been made in the apple store in a matter of a couple of minuets with machines that aren't even on the same table. Thoughts? Thanks!
