Found this from Marco Arment, who was under fire for his own Surface experience. I think a lot of what is said in this article matches my feelings about Windows Phone. I really like the look and feel of Metro UI. I love the Live Tile concept. I think the OS is beautiful and inventive.
But every time I think about leaving iOS and the investment I made there for something like WP, I realize that I am grading on a curve. The lack of ecosystem is a huge deal. The lack of systemwide notifications system is a big deal. Lots of little things that are missing is a big deal. It’s really a shame.
Microsoft is doing the most interesting UI work of any major software company. Think about that for a second. I wish this was actually going to place some competitive pressure on Apple.
