Santa brought me a new 4th Generation 1 Gigabyte Time Capsule (Model number MC343LL/A ) for Christmas. I was all excited to set it up. However, when I was doing a search to confirm that my model number was indeed the newest version (it is), I read all the horror stories about Time Capsules dying after 18 months. So what does everyone think? Should I keep the Time Capsule and hope that Apple has fixed the less-than-18-month life expectancy in this new generation? Or should I take it back? Any thoughts would be most appreciated.
