There's other 'basic' stuff broken too (see thread about repeating appointments).
The desktop *sync* software is actually OEM'd from Intellisync, I think. I don't know if RIM actually maintain this, or get Nokia (who now own Intellisync) to do it. So it may also be a case of what the Nokia/RIM contract can deliver and when, in terms of bug fixes.
As the features increase on RIM hardware and software, I personally think we'll see less stable software and a few more bugs in released software.
This reminds me of Palm in their earlier days. Early devices had a crudish UI, but what they did worked VERY well, was stable as a rock, and battery life on their devices was ground breaking. Then with "creeping featurism" and market pressures we got colour screens, wobbly stability, a more flashy UI, and more average battery life. Sound a familiar path?
