I had Nokia 5110, 3310, 6610, 6300 an now the N900. So this is my first smartphone I have looked into the smartphone area every now and then, but got disappointed with the features eventually. N900's full web support persuaded me I must say I am very happy with the phone. The way SMSs and IMs work was a nice surprise. Also, the management of connectivity is so much easier than in the 6300. I actually also like the fact that there are just two profiles - general and silent. I really do not need meeting / loud / loudest ... timed profiles would be nice though. On the the other hand, whennever I grasp the old 6300, I am amazed how thin and light the phone is ... and it was easier to use on the go for calls and SMSs.
