iTunes 10.6 vs iTunes 11

Hi I'm still using iTunes 10 and I'm wondering a few things. Most important is, if I don't upgrade will iTunes eventually not be able to read my library files, causing me to rebuild it from scratch? The other thing is, is iTunes 11 very different and are there problems or features that are hard to get used to?



Many thanks. :)
