Really, for the hour and a half it took for things to mostly stabilize, I was not dissapointed. I dunno, I feel surprised that people weren't expecting it to be a huge clusterfrack. I even prepped a drinking game for server crashes and login problems and such. The reality is that after that initial burst of Everyone Must Play NOWNOWNOW they will never come NEAR those needs again. The cost to cope with it and to have enough bandwidth and such for just that tiny period is, imho, likely to be vastly higher than it is worth. Even with the bad PR. It amazes me that anyone thought that would go differently, since I suspect it would take Google level distribution to handle it.
I am quite enjoying it. There are bugs, but I can cope. I wish they had just stuck with the open/closed b.net system they had in D2 that allowed single player, offline, whatever. But it doesn't bother me enough to forgo waiting most of my son's life to play it with him. :)
I wish I had gotten a collector's edition. But the cost was too much, and the b.net option pleasantly free with a wow sub I was going to have anyway. But I really liked it, with the pets for wow and the cool little soulstone USB drive that should have been 8 or 16G but is still cool.
