iTunes, a personal note: Their inventory of "old" music and specialty music like folk, country, Austin Progressive, etc., is very weak. If you are into Guy Clark, Townes van Zandt, Warren Zevon etc., you will find that Music Match has a far greater inventory, but Apple says they will have it solved by next year, far too late for Christmas. To sum it up: ease of use is super, inventory just OK. Like going into a beautiful grocery store with all the latest tech stuff but no butter and no fish.
