So I was surprised to come home one day to find our old Dell Dimension 3000 replaced by the new 20" iMac. It's so great, lightning fast, minimal noise, and the keyboard is really quiet too (though I wish it had the full number pad). My one grip is the mighty mouse. Not only does it not match, but it's kind of loud too. Anyway, I was wondering what do I do next? What applications should I add to make my apple experience go even smoother or whatever? Also, I'm looking into getting a wireless router and an external harddrive (for backing up, and to get all of the files I still want off of the old computer). Would you recommend the 500gb Time Capsule for this? Or should I get a separate wireless station and external hard drive? Cause I don't even know if the TC would work with the Dell, seeing as it's almost ancient. Thanks for your help!
