I use a Samsung i550 atm and encounter absolutely no problems with rSAP. Maybe because it is based on the older (more reliable) S60 v3.

But like you I wished I could return to Nokia. If the N97 would be better hardware wise (like the N900) and use a slightly updated S60 that could make use of such a better hardware I would own one already.

But one thing is for sure: I would not want to miss rSAP. Never regretted buying that equipment for my VW because it is simply the best out there...
