Doesn't bother me in the slightest. In fact I enjoy it and keep the messages. 90% of the time it's because I've beaten someone online. Those people I love cause you can just keep turning the knife and there is nothing they can do.
I'm in the same boat. I know i'm getting one just a case of when I can find a really good one on e-bay. But anyway the reason I post is Amazon are selling the 32GB memory card for £39.99 which is the cheapest i've found here in the UK.
