After much thought, I am on the verge purchasing a new 11" MBA ultimate. However I have heard some talk around the web, and on these forums, that there may be some performance issues when using Netflix Instant. Owners of these devices, have you experienced any issues when streaming HD content, Netflix or otherwise? The issues I've heard seem to be centered around the 11" 1.4Ghz 2GB RAM MBA. I was hoping to avoid these issues by upgrading to ultimate. Has anyone with a 11" ultimate experienced choppy video when streaming Netflix which was attributable to hardware limitations? Any insight would be appreciated.
