Hi all, Would the 11" MBA with 4GB ram have any issues with playing videos via VLC (downloaded media, not streaming media)? What about if hooked up to a projector and projecting them via VLC? Would it handle streaming video on YouTube well? Do the current GPUs affect either of these things? Also would whether I have an i5 or i7 processor effect either of these things or the ability to multitask? (Assuming I pick the 4GB ram regardless.) I recall someone saying 1080p videos lag a bit for them sometimes, but wasn't sure if this was due to the GPU/RAM/or what. I'm more concerned with the playing videos on VLC as this is what I tend to do most when showing media via my computer (currently an MBP). TIA!
