I've been a little active about the MBAs lately, but I never ask if its perfect for me. So it's not going to be my only machine, I have a quad core PC for gaming, etc. But how is the performance of the 2.13 MBA with streaming video and streaming audio? I'm going to be using it primarily by watching streamed or downloaded lecture videos/audios, Office, and reading pdf files of medical articles and of course the occasional HD videos, hulu, itunes. And I will be bringing the laptop to lectures and labs. Is there any lag or stuttering when watching videos? How about opening and reading pdfs? Is there any lag? I'm just wondering because I am currently using a 3 year old Thinkpad R61i which has 2GB of RAM and Vista, and as I'm typing this now, it stutters a little bit, and watching a video also lags and stutters a bit. (My connection is pretty fast). And when I open a medium size pdf file, it lags and stutters and makes it frustrating. So even though I have a fast gaming PC, I would really prefer to only use it for gaming or video encoding. I want to use the MBA for everything else. I'm worried if the RAM is gonna be a bottleneck and cause stuttering or lag. Anyone with experiences with the new 2.13 MBA, please drop by. I want the very best laptop before I drop in the money. I appreciate the help.
