I have had my MBA 1,86GHz rev. B SSD for a week now, and I will send it back to Apple Store, and go for a MB instead. I am using Plex as mediaplayer, and with my old white MacBook C2D 2.0GHz from 2006 I could play 1080p videos with no problem. The same movies stutters on the MBA, and the fan is loud. Now I have to sell the external soundcard I bought just to be able to get 5.1 digital sound out from the MBA. My test movies are 1080p encoded in h.264: Planet Earth in ts container, and Letters from Iwo Jima in mkv container. I really thought that the faster bus, memory and disk would compensate for the lower clock-speed comapring to my old white MB, but it did not. Probably in the future some mediaplayer will use hardware-decoding in the GPU, and then the MBA can be used as HTPC. But I can not wait for that, I want to watch movies now! There are also a small problem with EyeTV. When choosing the highest level of deinterlacing (progressive scan), there are also stutters. This also worked fine on my old MB.
