I don't know about your family, but my parents are blind for computers. Buying a computer for my mom would be an ideal, but I don't think she can handle the updates, I don't even know how to do it myself,,,,,,, You are right about I-Pad, it's the best choice for starters, I hope she likes it!
I was planning to give you a suggestion for fireworks in LA when you come down here, but I guess after seen the fireworks in DC, nothing will move you anymore,,,,,,,,,but if you happen to be here in LA on next 4th of July, you might want to check out the Queen Mary stay over program. The fireworks is Okay, going off right next to the ship, but unfortunately the music doesn't really go with it. However, I have to mention the best part is you can go directly back to your room right after the show, no trafic hassles!
Is your wife still working in LA? Are you moving down here by any chance?
