Thanks for all the good links Hockeycrazy.  I'm in my late fifties, been trading for years, made some, lost some.  Trading in and out is a way to get knocked out, as I know (AAPL at $22. Tech Cominco at $4.5, SLW at $4.  I lost on all these plus many more.  Rim may be on to some leading edge technology with a Mobile computing device and M2M, I like the diversified approach they have.  I think that Thorsten Heins did a lot of trimming and may have pulled a rabbit out of a hat, will see when BB10 is launched but I don't want to be left out again so I have my core position that will be a hold.
