While we're trotting out anecdotes, I have heard and experienced only the opposite.
One friend in particular who was given a windows phone by his large, seattle-based employer (ahem) had no end of trouble. The UI was great, but basic functionality was terrible. The thing could never handle SMS--we had to call him constantly, just to let him know what was going on, then we all would sporadically receive 4-5 texts from him that made no sense out of context. It was a nightmare.
