Let me preface this with the following: I own a 17" PB G4 that I love, but it has a large crack in the screen and the vertical line problem (see here) and it's due for an upgrade. The MBP was a logical choice, and I am certainly going to wait for the new ones expected in Sept. but I have been tossing around the idea of going with a Sony Vaio Z series. I really don't want to switch to Vista but I am going to medical school in a year and my uses will be limited to some video work (Adobe Premiere I guess, even though I love FCP), MS Office, email, etc. So, although I would miss the Mac OS, I wouldn't be doing as much graphics work that prompted me to buy my PowerBook 3+ years ago. Here's why I am tempted to go with the Sony: 1. Montevina - faster FSB, 2.53 ghz chip, DDR3 memory 2. 3.42 lbs (this is HUGE for me) 3. 13" display with higher resolution than 15" MBP (1600x900 vs 1440x900, I don't mind straining my eyes) 4. Up to 9 hr battery life with extended battery 5. 320 gb HD (option of dual 64gb SSDs, but I need the extra space) 6. Switch on-the-fly to integrated graphics for longer battery life 7. HDMI 8. Carbon fiber / aluminum chassis 9. NVIDIA 9300m GS (yes, only 256mb, but not faulty like MBP graphics cards) All together, without the dual SSD & blu-ray options, there is only a $100 price difference between a loaded 15" MBP and the Sony. Of course, the new MBP might match these specs, but it does have a lot of catching up to do. Do people think the September update could even come close to these specs? I don't expect much of a change in the weight/size, but how about graphics/HD/battery/high-res display? Also, I know this might not be the right forum for this question, but is it possible to predict whether a system with these specs could be "hackintoshed"?
