Perhaps they should start working
on making OSX run well on a Dell laptop (a company
who DOES seem to support their hardware quite well).
Sorry, but I'm not ready to write off or even compare Apple to Dell. Apple service has been great. Perhaps you need to call Apple (800SOSAPPL) and have a Dell user call them to compare what is going on.
I think Apple is a great hardware company
and software company. It sounds like a glitch has occured in the drive updaters and/or interference with other updates performed.
Talking to support is what they're there for. And it seems to me that when called on it, they are more than willing to escalate an issue past people that just answer calls and go by the 'script'. That's just one users opinion, I could be wrong.
Don't count Apple out because they have hit products. This has been a long time coming (I know, having been a Mac user from the bad ol' early days), it's a challenge being out front now, but a pleasant change for Apple, I'd bet, with two hit products.
OK, wait for it.... Apple's collective sigh. Now let's get back to work.
