ios 7 woes

I've heard about this on the Internet, but nobody seems to know the answer: Ever since updating to IOS 7, my iPad 2 randomly locks up. I have to press the home and sleep buttons at the same time—and even then it doesn't always come back! It's thrown it into recovery mode 4 times now...

Anybody know what the problem is? Is there a fix out there? Why isn't Apple offering another update to IOS 7?

This time it really died...the Apple logo is on the screen, but it won't move. Won't shutoff, won't respond to plugging into the Macbook...I hate computers!

Update: it came back—again! But this is getting old...
