My dad has offered to buy me a Mac since he and my mom converted a while back, but I never took him up on it because he'd really only be buying it for me so he could come to me to ask me questions. I really like not having to provide technical assistance.
You should definitely take him up on his offer. You'll be amazed at how little technical assistance is required. The probablility of you phoning him with a question is greater. It's difficult at first for a long time Windows user to understand the simplicity of the UI from Apple, but over time you come to love it.
Disclamer: I'm not an Apple fanboy. I own many different systems and OS's and in my life, they have all had their merits at one time or another. You owe it to yourself to see what else is available.
