Hi there! So I've had this gorgeous Macbook Pro for under a month and this problem has actually been happening since the beginning. I thought maybe I just expected too much finally getting a decent machine after coming from an old Toshiba laptop, but this is definitely worse than the performance on my black plastic macbook from 2007. I'm seeing beach balls once every five minutes at least but often once a minute, sometimes even when I'm just watching a YouTube video or reading a text document in Safari. Sometimes the lockup is with a beach balls but often everything just stops and a beach ball isn't even shown. I heard about the recent firmware update but I just have the standard 160gb 5,400 rpm drive. Any ideas? I'm also having trouble deleting some files. Whenever I plug by 1TB external in some files appear in the trash that cannot be deleted (not even with option or fancy terminal tricks). But the problem persists even when the drive isn't plugged in. Recently, this has happened with a folder on my main drive to. Where I will delete it and it will disappear but wont delete and eventually it just ends up back on the desktop.
