I'm planning to buy 2011 MBA 13" base model to replace my old trusty 2007 white MB.. So to make use of the MB, I'm thinking to use it as a media server, by connecting it to HDTV, attach 2 or 3TB of external hard disk, and connect my ethernet connection to it to share my internet ( I don't have any wireless router so this MB will also be that) I'm going to use XBMC or Plex to stream media. Also planning to use splashtop (iOS app) so I can remotely connect from my iPad. Now the question is, do I need OSX lion server? what other feature will it offer? Any cool implementation with it that fits my need? Thx in adv.
