Yah another one of those posts. My 11" base model just got here...now I'm second guessing the choice. The only demanding tng I do on my old 15" is photography and lately for my couch activities I've been using an iPad. Problem with the iPad is text entry..it just gets old. So my thought was replace the old mbp (2.4 pre unibody) and the iPad with the base MBA, and actually force myself to go to my office where I have a much faster quad core machine to work on photography..dual monitor setup, quad core, 8 gigs ram..and an actual mouse. I figure using that machine for my photography is a good idea. So that said I was thinking of transitioning all the data and photography stuff to the desktop unit, using the air to couch surf and take out and about. My thoughts in store were that the 13" just wasn't small or light enough, and after carefully checking activity monitor, even trying on my mbp I couldn't get past about 1.8 gigs of ram used withoutrunning major Photoshop stuffs. In store the base 11 felt pretty snappy too, even launching every app in the dock at one time wasn't really an issue. So my brain says, this is probably just fine if your lazy ass will go sit at a computer for photography...then my buyer's panic side says, dunce, go get the machine with faster everything, higher res, twice the drive space, sd card, and double the ram...the problem there is, it's 40% more money. Since I am selling the iPad and mbp I can afford the higher end model..the original thought though was that it is unnecessary after using the one in store. Without photos or music I doubt I'm using more than 20-30 gigs.. So anyone have the same kinda thoughts, any regrets on the base 11? Anyone regret not getting the smaller unit who went 13? I know the knee jerk reaction is to say moar are betterer...but given the usage scenario, what say you..I'd prefer not to eat a restock fee from amazon, but sorta feel like unless I use it for a few weeks, I'm not going to know if I hit a ceiling. Sorry for the similar and long post..thanks for taking the time.
