I agree with many thing you have pointed out. I feel that Nemo would have been a great place UI wise to start from. As of right now I'm not a fan of the plasma mobile UI. However with large screens some of their choice do make sense.

I was hoping that with Tizen, Web OS, Maemo, Meego and even Blackberry 10 they would all be able to share apps with qt and etc ... there by give open software a group chance to be a large selection of software to run on phones. Sadly never happened.

I can't complaint about people spending there time, just wish it would be more cross pollination of efforts.
