So you re-sync 32GBs everytime you sync? May I ask why? For 99% of the users, syncing means downloading new podcasts or adding a few songs they downloaded. For many of us, wireless sync'ing would be a huge feature addition.
No, but it copies files you've altered too, including play count alterations I *think* (it definitely used to with older ipods, and my first gen touch, but I haven't actually bothered plugging in my 3rd gen touch since initially putting my music across to it since contacts, todos, email, calendars etc all do wireless sync with MobileMe.
IF (and if someone who knows better says otherwise I'm not arguing!) ... IF it does still copy every file with any change, including playcounts, then if you actually listen to your music you are increasing the sync data quantity (and thus time) substantially.
Personally I'd love to see wireless sync as an option since I use separate chargers, but not at the expense of USB. Even if you had N it would still be vastly slower. 300Mbps is the peak bitrate, not the actual rate you will get data once overheads and distance and walls etc are taken into account.
As for people saying that other devices sync over bluetooth, there are three problems that spring to mind with this...
1) I doubt those devices are syncing music or videos over bluetooth and if they are it would be horrifically slow
2) It would be horrifically slow. I realise this is the same as 1) but it would be SO slow it really needs listing twice. I've had a phone where you sent music to it over bluetooth, and it only had 1GB capacity, and I still lost the will to live long before it filled up.
3) Since it wouldn't be much use for music, that leaves all your P.I.M. data etc, and Apple don't want you using Bluetooth for that, they want you to buy MobileMe (for good or ill)
