Windows Phone has excellent OneNote and Exchange support, it is the only touch screen keyboard I can type accurately on and while there are apps I'd like to see that aren't there - a Sonos controller being top of my list - there are plenty of useful apps and engaging games, to the point that I have more apps on my personal phone that I've ever had on any platform.
Does it have flaws? Of course. It's still the best mobile OS Microsoft has ever produced, and an excellent mobile OS in its own right, both of which are significant milestones. I've been using words like beautiful, elegant, charming and whimsical ever since I first got my hands on the phone - compared to the suspicion with which I approached it when I'd only seen presentations and specs. Windows Phone is an OS that you're not going to appreciate without using it. And ultimately, the best technology is the technology you use and want to keep using because it makes your life better.
In a quirky list that includes the Roomba vacuum cleaner and the Proporta waterproof gadget bag, that's high praise indeed for the latest version of Windows Phone. Read the full list and the thinking behind it, over on ZDNet.
