This is another one of those "should I" threads. I have a 2011 11" base model 11" Air with 4GB of RAM and the 64GB of storage. This is my only computer. I have worked hard with keeping my iTunes library on an external drive and keeping major files off of the main storage. I am sick and tired of worrying about what I can and can't put on my computer. So, the question is: Should I grab a 180GB SSD via OWC or sell the Air and get a base model 13" Pro? I would have to add an SSD to the Pro. Either aftermarket or BTO. Once you go SSD, you can't go back. Of course, people are going to say that it is all dependent on my needs. But put yourself in my shoes and let me know what you would do! Thanks a bunch in advance!
