After being thoroughly disgusted with Windows Vista, I've finally decided to make the switch to Mac. I originally planned on waiting for Apple to release refurbished models of the new iMacs. However, my university is clearing out its stock of the old iMacs and is selling the 24" model (2.16 gHz, 1 GB RAM, superdrive, etc.) for 1299 with a wireless keyboard and mouse. Is this something that I should go for? Or should I wait a few months until the new iMacs start being released as refurbs? I like the look of the new iMacs and, being a PC user for many years, I am scared of upgrading the OS. Any input would be helpful.
