I expect a well-built physical device and reliable cellular radio -- just like other Nokia products I've owned.

I expect an easy-to-use interface that my non-technical family can operate, and which is free of bugs.

I expect an open platform that will enable me to introduce bugs.

I require, but don't immediately expect, push email. (That's the only thing that has kept me from pre-ordering; I have BIS on my 9300, and I'm a slave to it.)
