Sorry to hear that you are not having any success with your Mac. What was the deciding factor that prompted the decision to sell the iBook? Must have been something pretty terrible and something that you were unable to overcome.
What are the details on the iBook? Speed, memory, HD size, "the loaded" stuff?
You would probably be better off selling it on eBay than going with a reseller who will give you 50% of the original price and then offer it for sale at 90% of the price. Your husband is probably correct. You should be able to get much more selling it yourself. If you have a local Mac Users Group, speak with them about it.
On the subject of software, in most cases the software just moves across with the machine. In the case of QuickBooks, which needs to be registered for updates, you can contact them and tell them you are selling the machine and the software. Ask them to remove the registration for it until the next person registers it. Don't expect the inclusion of QuickBooks to increase the value of the machine.
Sell the Extreme Base station and the Express base station, separately. Someone sold you a bill there. With only one machine you did not need anything wireless to connect to the internet.
One other thought to bear in mind. If you buy a new PC, it too, will be totally different to anything you have used before. You will be surprised how much XP looks like OS X. It is also able to run addition software, that your iBook couldn't. Stuff like Virus's, Spyware and Adware.
Let me know the details and I'll see what a good value for that machine is.
We have given using the iBook our best shot but find that it is not the computer for us. We have always worn out our computers so we have never faced selling one before. We went online to a re-seller of Apple hardware and used their estimater of the value they would put on the iBook; in six months it is priced at 50% of the original cost, plus we would have to pay shipping charges to them. And I'm not sure they would want the Extreme and Express base stations. My husband hopes that we could do a little better by selling it ourselves.
My question is two-fold:
1. What happens to software when you sell hardware? For example, will Quickbooks allow the new user to register the software and use it/upgrade it even though we already registered it?
2. Does anyone have any experience selling an Apple? Should we just go with selling the computer at 50% and take all the software and base stations to the dump?
