It's great if you have an iPhone and want the syncing features, everything else has free alternatives (though, not as sleek) as MobileMe. Not worth the $99, and you can get them for much cheaper than $69, as well. MobileMe boxes aren't tied to any serial numbers and all that is really in there is just an activation code. Check the usual suspects like Amazon, eBay, etc. I was able to get one for under $50.
