I really don't like it. I loved the other microsoft logos, such as the new xbox logo and the new office logo because of how well they used white space and how effective the simplicity is in it. But to have this as their main face logo, it seems very sloppy and just not well executed. The type looks off, the ligature seems out of place with the rest of the kerning and the whole thing looks unbalanced and clunky.
I could be swayed by the fact I've already seen a near perfect conceptual microsoft re-brand but I still stick by my opinion that this could have been done a lot better.
