Hi Joe - sure, what do you want to know? I love it, the screen seemed a little small at first but you get used to it pretty quickly. It seems a little zippier then the original model, not sure about the updated ones, but I find it fine for mobile work. I have Apache/MAMP running on it delivering Wordpress multi-site for development and it's fine for that too.
I use a USB broadband stick. This is actually more convenient than the old Air as you don't need to use an extender cable. And there's still a spare slot (woo hoo!). Only thing lost is the illuminated keyboard which I thought I'd miss but actually don't, in fact I'd forgotten about it until writing this.
