My old external hdd drive died and I've been reading up on the Time Capsule. The things that interest me the most are it's extended network capabilities like the 5.0 GHz function, more range and wifi speed of 450 mpbs. Also it's ability to let you acces data wherever you are. But I have a few questions regarding that. Can I watch high def movies on my MPB if I'm away through my TC at home? Because I expect its speed to be an issue.
