I've been considering the ATV instead of getting Comcast in my new apartment, but have a couple of questions (both of which likely showcase my computer ignorance, so apologies in advance). 1. One reason the ATV seems a tempting option is that my iTunes library is using up all the space on my puny MacBook hard drive. Being able to keep my stuff on an ATV instead would be terrific, as it would free up a good deal of space for me. But I can't figure out whether it's possible to use the ATV in this way, or if in fact iTunes would always automatically download anything I order on the ATV to my laptop. 2. I can't use an ethernet connection-- it will have to be wireless. Is there any reason the ATV's streaming capabilities would differ from my MacBook's? That is, can I use my MacBook's playback of Hulu, etc, as a guide to whether I'll be happy with the ATV's? Thanks, very much, for any replies. General advice/opinions/experience with doing this are also very welcome!
