I tried 0.04 last time there was an announcement (not long ago) and it really, really sucked. I use Komodo from ActiveState now, on both Windows and Linux. It has Syntax Checking, coloring and lots of other great stuff, it works beautifully, is based on Mozilla and generally kicks *ss. :)

Moreover, it supports lots of other languages natively, and yet more with highlighting etc. Give it a test spin, you'll see what I mean. First time I ever liked an IDE over my normal text editors, no matter how many I've tried... :)

I think it is only about $30, too.
