I will be going to college next year and am in dire need of a new computer. I am all but set on getting a 13' MBA (2.0GHz, 8GB RAM, 512GB flash). I could potentially get the computer now, but would it be a better idea to wait until June(?) when the refresh the MBA? I would like retina display on the air, but I do not think that will be happening this year...Regardless, has there been any verified rumors about what is going to happen to the airs later this year that I would potentially want?
