Six months after buying a 1.8GHz G5 iMac w/ SuperDrive, I'm wondering if I should trade. My local Mac store will do trades for other computers or put the value towards a new computer purchase, so it's on my mind. I was wanting an iBook 12" or 14" w/ ComboDrive but my wife talked me into the iMac because she wanted to use it as well. She uses it for e-mail maybe once every week and that's it. The iMac is great for my Web design work, but I'm getting out of that soon. Right now, I'm just using it to get online, check e-mail, use Quicken for bills, etc. It's just more computer than I need right now, plus I hate that I can't carry it around with me through the house and on trips. So, I'm wondering if a trade would be worth it. I'm not sure how much I could get for it, but I paid $1800 after tax and Apple Care. I'd like to get a laptop for around $1100 and if I get more for the trade, I'll just buy a full-size keyboard for it and maybe a few other extras. Specs: 1.8GHz G5 17" SuperDrive 512MB 10.3.8 Specs of the laptop I'd like: 1.2-1.33GHz G4 iBook 12" or 14" ComboDrive 512MB 10.4 (even if I have to buy it later) What do you guys think?
