I was very happy with a Blackberry for a long time in my business career.
When I retired a year ago, I bought an IPhone 3GS and was delighted with it.
Recently, I bought an IPad 2 and that has become very addictive. I have added an Apple TV , and am eagerly awaiting IOS 5, and ICloud.
I am 69, a keen Rotarian, and enjoy playing golf
