I routinely tape the walls around windows these days. Aside from the cost of the tape I've had much better results. There are some issues with tape but the alternative takes so much longer and you can still have problems getting it to look properly edged.
I have done both for many years though and cutting in without tape used to be a delight with a trade oil based eggshell on top of a really thick oil based undercoat. I do miss some aspects of those days.
In fairness, on a normal redecoration I often aim to finish on the walls because of that sort of thing. Leaving the woodwork a few days and then taping and one final touch on the walls can give a really nice finish. Sometimes it just can't be done though.
