I am a PT graphic designer & photographer. When I work, I'm usually running Ps, Il and Lr all at once, but I don't usually do any very heavy projects. I'm currently living out of 2 computers: an HP mini (running Linux) and a 2007 MBP w 2.2 GHz Intel Core 2 Duo and 2 GB of ram. I need the portability for school and love the 11" MBA and figured I would invest in a good monitor for when I need to work. I'm getting mixed opinions on whether or not the MBA could be a solid enough MAIN computer for me, but people seem to think it would be. The specs I'm looking at are the 1.7 GHz Intel Dual-Core Core i5 and the 4 GB of ram (which, compared to my current MBP you can see is a HUUUGE difference). Do any other digital media professionals use a MBA as a main computer? Do you think these specs can handle it? I'm a FT otherwise-unemployed student so I'm really trying to keep the cost to an absolute minimum. Thanks!
