I currently have the unibody 17" MBP and this is my 4th unit and I've had enough because it's faulty as well... see this thread! I wanted a MBA before I got the 17" MBP but that was when it was still the old design, when the design was updated to the unibody I just had to pre-order it! It's my first ever mac and I love it, but the issues I've been having have annoyed me a lot. I'm thinking of getting a refund from Apple and getting the 1.8GHz MBA with SSD instead. I love it's form factor (I'm a gadget geek at heart!). I will be using it as my primary machine, will be using it for: VMWare Fusion Photoshop Microsoft Word Burning DVD's using Roxio Toast Watching films Do you think it would be capable for what I want it for? Would I notice a really big decrease in speed from my current MBP? Would it be hard to switch down to a smaller screen from 17"? Does it have really noisy fans? or is the system completely silent? Do you think I should get it now or is a Rev C near release?
