When have 'Industry forecasts' ever been right?
Every time I see some forecast from IDC or whomever, it ends up getting followed up with "Well, I guess we were wrong, but here is a list of excuses we didn't see coming but everyone else did"
Seriously, how can anybody not take into the account that when people pay over $500 for a tablet that they are going to give it to someone else rather than have it collect dust in a drawer? Especially since current tablets aren't all that much better than the previous model, which still work quite well for most uses.
