Everybody's a critic ... even me.
Actually, I liked your initial design. It's simple, elegant, not gimmicky. However, it needs some polish. Here are my suggestions: (Sorry, I don't have Gadget, so I put mine in Century Gothic bold.)
1. Fix the kerning. See how the spacing between the letters is adjusted in my example? And don't just tighten the tracking on the entire name. Do each letter individually based on it's individual shape. For more information, Google "optical kerning."
2. Make the colors more Win and Mac like. The red and blue you picked are reminiscent of the platforms color pallet from five years ago. I updated with a more Mac-like blue and a red that evokes the "X" close box from XP. 'Course I had to adjust both color so they didn't clash. Doing this makes the logo seem more current -- which is essential for a tech company.
3. Savage Henry makes a fine suggestion about the interactivity between the Mac and Win elements. However, the drastic comps that followed, frankly, scared me.
I propose a much more subtle interaction, but interaction none the less.
4. I think the tag line "Suddenly it all connects" needs to be anchored to left. Because of the backslash-like slant of the first descender in the "W," the centered construction looks off balance. The same "W" problem makes left alignment a no-go. However, the right alignment gives it an anchor, so it looks solid. Do note, however, that I let the period float past the right alignment. This is "visual aligning" and is similar in concept to optical kerning.
Anyway, you original logo was, IMHO, far superior to any other options above on this page.
Sorry to sound so preachy. :steps down from high horse:
