It's day 20 with the Nokia Lumia 920 and I'm two-thirds of the way through the challenge of using both Windows Phone 8 and a Nokia smartphone - two things I haven't done in a while.  Going back to applications, there are a lot of things missing on Windows Phone 8, and I find that (lack of) ecosystem to be a very important thing.  It's a challenge for people that enjoy apps and the ease of use that often come with them.  That's my biggest issue - if I had to pick one thing out of 20 days with the phone, it would be that.  Switching gears, I've gotten used to the messaging and notifications on Windows Phone 8, and overall, the multitasking works relatively well.

Let me know what you want to see in the final ten days by tweeting to me @PhoneDog_Aaron!
