I am a windows guy I havent owned any apple hardware but itouch and ipad and just got a iphone for the wife. I really like the 13 inch macbook air I was using it in the store when we got the itouch. I am currently using a sony vaio laptop i7 8gb with 500gb harddrive extend battery.. Battery life stinks btw. I use the laptop mostly for RDP to MS systems, Email chat and Word excel. Some photo shop editing. I am sure some apps I use are MS only. I have been told parallels is the way to go for using MS only software. Will 128gb get you very far or is the 256gb worth the extra 300 I assume I could a nice usb drive for my extra files I might want to take with me but then I have something else to carry. I am looking for this to be my primary laptop since I will ebay the sony or pass down to one of the kids I am looking at replacing my MS stuff as they die with apple if this goes well. I looked at the macpro in the store also. I liked the air for the weight battery life and the screen looked much better. I will use this alot in low light in the bedroom when the wife watches tv.
