Situation at the moment is I have a 27" iMac for pretty much everything as my main computer which does everything from CS5 to iTunes to University Assignments. I also have a Late 2008 15" MacBook Pro 2.53/C2D/4GB. Since I've had the iMac I haven't really used this for much more than the web/social/videos. Also have Windows 7 running on Parallels but only use MSN and a few other programs in that. But when I have it running, I will ALWAYS be browsing in Safari and watching videos. I also have an iPad which is not really getting used at all anymore. I pick it up occasionally if I have turned off the MBP and want to check the web quick! It will also get it's use next week when I fly to New York. Now whilst I'm there I plan to take alot of pictures and upload them straight to the iPad. So now I'm thinking, if I sell both the MBP and iPad and replace for a MBA (would be 13" with 4GB) that would fit the bill nicely and would quite easily beable to handle the tasks I carry out. But, I am a little worried that I will miss the MBP! Will I notice a difference by dropping down on the processor speed? I'm not sure what to do at all....Anyone in the same situation?
