The font in the "Lean. Clean. Agile Machine" are a little aliased. At first I was willing to overlook that, thinking you had embedded fonts, but seeing that it's an image, and a background-matching JPG at that, it could be easily fixed.

Otherwise I like the look of the site (though I haven't had much chance to use it yet.) The "Login" and "Password" areas look a bit off. I'd either shrink the text inputs or increase the font on the label. Also, the gold border on focus just sits wrong with me. These are of course, personal opinions, so please confer with others to see if I'm the oddball, but it strikes me as overlooked.

Regarding the copy, "a web-based software" also strikes me as off... perhaps replace with "a web-based application?"

Also the footer doesn't match the page alignment of everything else. If it were my site, I'd bring the left and right margins in line with the rest of the site, as they're otherwise hard to find.

Aside from that, I'll parrot that it needs a "Try it now" type of button somewhere, and you should probably lean down what you're asking for at registration-time. I usually try to restrict registration questions to only the things I really need to make the software work, which is usually less than 5 total questions.

Altogether though, it looks solid, and I look forward to playing with it more.
