I was one of those clowns that was in the line up the morning of March 16.
Not because I wanted to but because one of my staff members was leaving and she always wanted an iPad.
Standing in the line up I got a little peved because I realised that all this waiting and I can't even play with it when I get back to the office due to it being a gift for someone. So I did what any other person in the same situation would do.... Buy two.

I had the iPad 1 and side by side I can tell you the screen on the iPad 3 5hits all over it. Even along side a workmates iPad 2, it's chalk and cheese.
I got the 32 gb 4g one, don't see the point of having a mobile tablet that you have to constantly be hunting for wifi points in order to use it. It's been funny watching the android crew slamming it though because here in Australia our 4g network is... well... primitive... Unfortunately due to us being behind the times, we still have the Analogue TV network here, which is using the 800mhz spectrum that the iPad uses for 4g. Hopefully the government speeds up its canning of it so telco's can start putting up towers in that range.
But all in all, upgrade from a 1 - 3, yes worth it i believe. 2 - 3 not so much. Battery life is fantastic, screen is just awesome.
