I, like many, have been waiting a long time to upgrade to a Mac Pro, but I just can't wait any longer for the refresh. I'm running a max'd out G4 dual 867 MDD and it just can't go much longer so I have to buy now. My question is should I get the single quad core tower or go with a 17" i5 MBP (8gb ram and 500gb 7200 HDD)? I've never had a laptop but would appreciate the ability to take it with me when needed. I am a graphic designer, so I use Adobe CS a lot and expect it to perform. I am aware there will be speed differences in the tower vs laptop. But I'm wondering if I would miss or notice it that much coming from my old mac. On a side note, I also run a PowerMac G5 (dual 2 gig) at my day job and think it performs excellent so I guess I would hope for similar performance or better. Opinions welcomed - Thanks!
