Samsung Galaxy S2 type of hardware with Meego and working Dalvik VM would had made me happy.
WP7 never will, and I highly doubt WP8 neither, unless MS transfers it to a open source license.

Well fortunately there is other phone makes than Nokia which prolly will do that. Nokia is history.

btw, you did not answer, how long you are willing to wait a high end WP phone from Nokia?
