says the guy with two macbook airs and a macpro...OP make sure you listen to this guy, i'm positive he's full of rational ideas.
BTW if the OP didn't mention the 17" MBP i would've never had mentioned the 13" MBP, which is both faster than the 17" i7 and his iMac he mentions and has just as small a footprint as the macbook air which is still pretty damn portable and light barring any iron deficiency issues that make 1.5lbs "noticeable". Yeah, I'm sure that external he's going to have to lug around with the air because of the limited HD size weighs nothing right?
Listen OP, if you're not going to find yourself editing any movies or using processor intensive apps then go for the air...obviously it looks cool as hell and you'll get the same performance of the MBP w/ssd. BUT if you think you'll be using your computer with any big boy applications that aren't found in the app store then you have to consider the MBP, especially for the fact that you're considering keeping the machine for a while and for god sakes listen to kohphiphi and myself when we say two machines are a pain (unless you use one solely for media and ****ing around on or need a backup).
Hey ******* no need for the smart *ss or condescending posts if you've got nothing nice to say, shut up.
I spend a few minutes here once in a while offering advice based on my experience. When I made my switch to mac, members here where REALLY helpful ... now that I've learned as I go I share my experience.
Now about your post
"says the guy with two macbook airs and a macpro...OP make sure you listen to this guy, i'm positive he's full of rational ideas" ...
Actually if you need the full picture it's:
Mac Pro dual ACD's, 13" MBA, 11" MBA ... in our main office my recent purchases include 24 and 27" iMac's, 2-3 15" MBP's, 2 15" MBP's AG, 3 13" MBP's, 2 MBA's pre-2010 update ....
Since I can have any set up I want and I've owned and USED every recent model of Mac except the 17" yea, maybe I am full of rational idea's
Maybe you're not capable of keeping two computers in sync but with just a little research and learning you'll find it's very very easy.
You write like carrying a portable HD is a huge burden, LOL, a portable HD 1 TB HD isn't much larger than a deck of cards and about 140 grams in weight. So carry a little light air and tiny HD or carry a MBP that weighs DOUBLE and takes up more space.
Where is the good advice in all this?
OP - You have the option of getting one computer two, that's great. As per my original post take advantage of that, no need to lug extra weight and bulk around with you everywhere if you almost never need it. Having an iMac at home for heavy lifting or just to enjoy working from two computers instead of one all the time seems worth it.
Based on my multiple mac experiences that's the best advice I can offer. My wife went from a 13" MBP to a 15" MBP then to an iMac and 2010 13" MacBook Air ultimate and absolutely loves the combo ... otherwise she was always plugging and unplugging her ACD and when mobile she was carrying far more computer than she needed in both weight and power. It's not about the Air looking "cool as hell" it's about the ultimate in function, light weight, adequate power, takes very little room in a bag ... excellent screen, keyboard it's quite a machine.
NO compromises.
