I'd wait for the next model to be released, they'll be around on ebay for years if you really want another one.

People always say, "just because something new comes out doesn't make the old one any worse".
I personally don't understand this, and I'm sure Darwin wouldn't either!
What about when everyone upgrades to flash n+1, when html5 is a standard and anything with less than 512mb RAM can't even render a web page.

Will you be playing the same tune then?

Adapt or die!
