Soon ill be buying a new computer - my budget is around $2000. Im thinking: iMac 21.5'' high end model with a 256gb ssd - $2100 or Macbook air 11'' 256gb with i7 and 8gb ram with a 24'' monitor - $2100 Ill be dual booting windows 8 and using microsoft office 2013, parallels 8, sketchup. So i could get away with a 128gb but would be better off with a 256gb ssd right? What do you guys think - my only concern is that its not worth me getting the macbook air because i dont really use the portability and like currently with my laptop i dont like to have power going into it all the time but like for it to run down for proper drainage of the battery, but find the 21.5 inch imac too small. Any suggestions?
