So I bought the a 24" iMac. I'm a switcher, but was a Mac fan until my LC died in 10th grade (can you guess my age?). Anyway, I'm having a really hard time adjusting to the wireless keyboard from my Dell laptop. Is the wired keyboard any easier? I ask, since I know that it is wider and includes extra keys. BTW, does the wired keyboard have an "end" key that takes you to the end of whatever sentence you're in. I really miss that. Thanks.
