How is snow Leopard? Is it worth the upgrade?
It's OK.... when things work with it. The OS works well for me, but stuff like CS3 and VLC and DVD Player bomb arbitrarily and frequently.
The price is right, but you should all wait for an update into .1 or .2 before getting it. There is nothing you can't live without on SL.
Knowing Mac, they'll be inundated with all the error messages by now and are beavering away at the big fixes so they can have a version to work nicely with the hardware coming onto market within the next 2 weeks.
No matter when they release an OS, they have a LOT of problems to fix. Apple, nor any company, have the breadth of use in their departments to find all the problems normal people will through their widely varied usage. Bitching about the flakey OS first release is useless: it's going to happen every time. Just stand back for a month and let Apple sort it all out before you purchase or install.
