IMac :: Use Wireless Keyboard & Magic Mouse?

I've been lurking around this forum for a few weeks, gathering information to decide what Mac I wanted to order. I appreciate all the information that is available here! I took the plunge this afternoon and thought I should register as I'm sure I'll have questions in the coming weeks. I played around with an iMac at an Apple Store a few months back and kicked around buying one. I really enjoy my iPhone and my iPad, but I kept thinking about the iBook G4 that has been gathering dust because I never really took the time to learn the Mac OS. Then my Windows laptop quit and I had to send it off for repair. I dug out the iBook and that put me over the edge. For whatever reason, I had no problems figuring out the OS this time around. I've been trying to figure out how to justify an iMac ever since. Today I ordered a refurbished 21.5" iMac from Apple's refurbished site. I ended up ordering over the phone -- I called Apple to ask a couple of questions, and when I mentioned that Amazon offered Apple Care cheaper, the sales rep gave me a discount on the Apple Care. Plus, I got a free (after rebate) AirPrint-capable printer. So, I think I ended up with a pretty good deal. After all that, I'll get to my question -- do you use the wireless keyboard & magic mouse? They seemed fine when I was using them at the Apple Store, but that was just for a short time. I'm wondering how I will like them when I'm editing photos or typing a long document (I deal with all the numbers I can handle at work, so I don't do much at home that would require the number keypad).
