Howdy, I've been (im)patiently awaiting the upcoming MBA, and I'm not afraid to wait longer, but I've been second guessing my use for one. I think my initial reason for jumping to the Mac bandwagon was to delve in some iOS development... just as a hobby of course (I do a little Android, but meh, I own an iPhone 4 and iPad 2). So I was thinking of just replacing my 2009 Sony Z (2.66GHz C2D, 1600x900 13.1in screen, 4GB RAM, 320 7200RPM HDD, Nvidia 9300M GS, etc etc) with a 2011 MBA (presumably a 13in ultimate). BUT, my Sony Z is still in pretty great condition (normal 2 year wear and tear, I suppose) and it's small enough for me to take to class, libraries, etc (as for some background: I'm an upcoming 3rd year electrical engineer). Common applications I use are: Windows office, Visio, Mathcad, MATLAB, Firefox/Chrome, FileZilla (I'm not too picky about FTP applications though), and presumably will be using more engineering software as my studies continue (maybe Cadence and what not). I use a couple photo editing programs, but nothing too intense and not too frequently (I'm a very, very amateur photographer). I also don't game (on my computer at least... I have a 360 and PS3). Pretty simple application requirements for the most part. So, I was thinking of just getting an iMac, that way I could have a pretty nice balance in terms of mobility and operating systems (portable Sony Z with Windows on the go, nicely spec'd iMac with OSX back at home). In the end, I'm torn. So I thought maybe the well-mac-acquainted forum users here at Mac Rumors could help me out (again, this would be my first Mac). I really, really like the 27in iMac, but I was thinking of going for the up-scale 21.5in with an SSD (I think a 27in with SSD would be out of my price range). I doubt I'd go for an i7 (though, I'd like to if I could, just because), and will probably upgrade the RAM myself in the future (if need be). Since my 2nd year, whenever I'm at home (erm, my apartment) using my Sony Z, I usually hook it up to my 24in 1920x1200 Samsung LCD, used in conjunction with a Logitech MX mouse (talk about an ergonomic mouse!). So I sort of have a dual monitor setup going on already, but sometimes my Sony Z overheats easily (oh, and it only lasts ~2-2.5 hours on battery on normal usage without being connected to an external monitor). Like I mentioned earlier, I'll probably be waiting for the next MBA to release, as well as the Back to School promotion (although, I can get the Intel corporate discount... which surprisingly sometimes isn't as good as an educational discount or anywhere near as much as you'd think it'd be). Anywho, let me know what you think. Thanks! Cheers EDIT: I guess the impending 2011 Mac Mini could also be an option, as I already have a 1920x1200 monitor and mouse. I also have a 2TB external USB drive, if that's worth mentioning.
