The new MBP's sound great, longer battery life, better trackpad, faster, perhaps cooler running it's got my interest But, I'm wondering if it's worth it for me to upgrade. Price isn't a concern and I spend a lot of time on my laptops, 12 hours or more some days. I currently have a - 15" MBP, mid '09 2.8 ghz 4 gb ram 512 vram, 9600m GT 256 ssd if I upgraded to - i5 15" MBP 2.53 ghz 8 gb ram GT 330M with 256MB 256 ssd OR go all out and order - i7 15" MBP 2.66 ghz 8 gb ram GT 330M with 512MB 256ssd The reason I listed the i5 option along with the i7 is I'm thinking the i5 may run cooler and quieter? If that's the case I'd prefer that. My uses are - CS4 for concept/design drawing photo / video editing, (hobby) heavy word processing, emaiing web surfing movie, video watching Or should I stick the the 15" MBP i have now, or if I upgrade should I get the i5 or i7? Thanks.
