I got my email with a discount code from SixApart today. 50% discount on a license, personal or commercial. I don't know if I can combine it with the $20 discount I get for having registered 2.6x, but if so then I'd get the personal edition for $15.
They have a LOT more developer information available for MT3. Too bad I don't do Perl, in a way…looking over the API documentation I think anyone comfortable with Perl could get real productive.
So I have these three incredibly powerful lightweight CMSes that I'm stalling about installing because I've promised an osCommerce installation to a friend (okay, it's my daughter's mom but we managed to stay friends, go figure). ExpressionEngine has the functional edge without question and is much less expensive than an equivalently licensed Movable Type, but then MT hasn't been a moving target for a while. Wordpress comes up short by not supporting multiple sites, but the tremendous functionality they added in version 1.2 (assuming it all works, I haven't tested it yet) brings it about even with MT3.
Given the pricing and capabilities of these things, SixApart needs to make a pretty serious move.
