Without stuttering ? The 1.3 ghz CPU has me worried since it is a ultra mobile chip, can anyone confirm if it can handle say Netflix Super HD or 1080P video playbook without stuttering or frame drops? What about mirroring the HD content to a tv? Thanks guys! I'm looking at the base air 13" , 1.3Ghz, 4GB RAM. My other option is going with a rMBP 13" but I've heard lots of horror stories from my co workers.
