Back are the days of ugly IE hacks, frustrating testing and rewriting stuff so it works in IE6.
A heartfelt "thank you" to Micrsoft for screwing over countless web developers who finally felt that they were able to really express themselves at least in the mobile world.
Also, dear customers, please understand that from now on any mobile work you are giving us will be much more expensive because Microsoft decided to release a phone OS in 2010 with a browser engine basically from 2001 (I hear it's not quite IE7).
And, dear end users, please understand that because of Microsoft, we won't be able to supply you with all the amazing new features in your mobile apps as quickly any more because, now, we developers will have to do additional work to make sure that whatever we are creating works in that new OS Microsoft released that runs a browser from 2001.
Myself? I'm off to hide in a dark corner and cry.
