I actually don't have too much of a problem with SE handsets, for dumbphones anyway... They're way better than moto or sammy, that's for sure! UIQ is better now than it was, but still miles behind S60 in the UI dept.
At any rate, if I was buying a dumbphone, I'd buy an SE over an Series 40 phone anyday...
...of course it's all academic, because i'll not stray from s60 again
