I can't cover all the new or updated items that will have relevance to me in the coming months in just one post so I thought I might pick one that really jumped out at me and run with it. Live Tiles.
What's New with Live Tiles(And why do I care)
Most have pretty much agreed that Live Tiles are pretty cool. Some use them more than others but when implemented well they are great! But, unbeknownst to me until Build, it turns out there can be improvements. The improvements come in a couple of areas, one of which had little to do with the Live Tiles themselves but has created a new demand on Live Tiles that I didn't expect. Each improvement has impact on the Developer and the User and both should take heed. The developer more than anyone needs to know about these at the risk of losing out to apps better able to leverage that "in your face" positioning on the Start Screen. In fact, all the improvements may overwhelm even this little post.
