Hey all, brand new Mac user here - my PC laptop finally died and being so frustrated with Vista (I've used Win 7 - I know its better but I'm not interested, Vista has ruined me on PCs), I went on Ebay and grabbed a used iMac.

First of all, the iMac is a 1.83ghz core 2 duo Intel with 2 GB ram and an 80 GB hard drive. The seller said he loaded a "fresh" install of Snow Leopard on there, but the machine came with no software at all. So what I really want to know are answers to the following (dumb?) questions :

1) How can I really tell if its a "fresh" install. Meaning, could he have just left his old install on there and deleted his personal files?

2) Are there any programs I should be looking for to get rid of? I know Macs rarely have malware and don't come with much bloatware but I AM just getting off a PC.

3) I have a 320 gb external usb hard drive that has audio files, pictures, and a few video files that I made using a PC. I'm sure the audio and picture files will transfer fine, but does the Mac do the whole ".wmv" thing?

4) I can just buy the Snow Leopard disc off Amazon or wherever if I need to reinstall the operating system, correct?

Thanks for the help guys, I've always wanted a Mac but could never afford one. Glad I decided to take the chance on a used model.
