Is anyone else seeing a lot of beach balls lately? I havent installed any new programs, changed a lot of large files... but I get a beach ball for about 20 seconds every time I open an email in mail.app, click on something in iTunes, or any other small task. Also, my backups havent been running... it just stays on "preparing backup" for literally hours. I have no idea whats going on... anyone else having the same issues??
