Hi there, I've been browsing for the past couple weeks, and have learned a ton from this forum. This will be my first Mac and I've gone back and forth at least a dozen times trying to decide between the MBP 13 vs the MBA 13. If I were to get the Pro I would upgrade the harddrive to the 128 gb solid state drive directly through Apple. The price difference isn't a that much higher, and I'm not incredibly computer savvy. I would updgrade the ram to 8gb myself, seems to cheap not do. I would then buy a 750gb hdd and replace the optical drive. If I were to get the Air I would get the ultimate w/ the 256gb ssd. I have around 50gb of music. I haven't decided for sure but will probably run Bootcamp or parallels. I'm in finance and a couple programs require windows. With that question do you guys recommend using the Microsoft office suite or Office for Mac. I have read there are some minor differences. I will mainly be using excel. I will not be doing any video editing, of high graphic applications. I work within a couple miles of my office and drive there so portability between the two is negligible. It will mainly stay at home. The pro is probably over kill for what I need. The computer I'm using now has 2gb of ram and it gets bogged down quite often though. My biggest concern with the MBP is the screen resolution, and with the Air only having 4gb of ram. I've used both of them for 15 min at the apple store and still can't decide. I appreciate all your help.
