You will. If you are new to Macs, you will get a hang of it in no time. I switched to Macs back in 2005 and I do not regret it one bit.
If you are a Windows user and want to make your switch easy, get the following programs:
Adium= Msn Messenger, AOL, Google Talk etc
Adobe Reader= Read PDF files
Firefox=Browser
Flip4Mac= Play Windows Media Player files
Openoffice.org=Word, Excel and Powerpoint
Parallels Desktop=in case you want to use Windows as well.
Toast 10=It is the Nero Burning for Apple machines.
Un-RAR=open rar files
VLC=plays every single media file out there
if you want office get it for the education discount. It is sold everywhere in the education version and there is no check to see if you are an educational customer. Microsoft knows this obviously.
