Basic photo Internet some you tube nothing too fancy and also e mail I'm into real-estate so I might something pretty easy to carry around
I am very limited as to what I can spend so I have an old Dell computer on it's last legs and need to replace asap. So I think the 11.6 might fit my needs
13" MBP.
It's really a no-brainer unless you want ultra-sexy over ultra-practical. MBA has a C2D chip. Do you really think Apple and other major s/w makers are going to be designing software w/ a crusty C2D in mind now that the low end 13" MBP is faster than last years high end 15"? Nope. Sure it will work...just not real well. The MBA is more flash than dash.
Get a MBP. Replace the HDD with an SDD -- very easy DIY job. Your MBP will be about a 1.5lbs heavier. Not really a big deal. It just won't be a head turner.
Absurd recommendation, especially since others in the thread were so insistent the OP provide a list of what he needs from his computer.
OP, the MacBook Air, any model, will be more than capable, and I think if you're looking for something easy to carry around for the uses you mentioned, then the 11.6" MBA is a perfect fit for you, and the only thing you need to consider now is if you have a need for more space than the standard 64GB drive.
