Cell Phones on Airplanes?

The EU is allowing Airlines starting this summer to permit customers to use their cellular phones on airlines.  I don’t expect airplanes to start dropping out of the air because of the phones interfering with the electronics, but I wonder if this won’t be a little annoying? 

I know when I am on the phone my conversation volume is louder than my normal talking volume. So think about adding airline engines to the mix isn’t that just going to create some bad situations?  Will customers be allowed to request new seats if they are sitting next to Chatty Kathy?

Could cell carries disable calling but allow for data or texting?
