First of all, it took 90 minutes to install.. on a 17" MBP. So, once I got past that, it seems like Tiger restarted much more quickly than Leopard. I get a blue screen for almost 20 seconds before it brings up the log in options. And then, once I get in there, applications are running really slowly.. esp. Photoshop. iTunes took its sweet time coming up too. Anyone else see this? Is it temporary while the OS adjusts itself?
