Hi sorodoros,
thank you, your informations are really precious. I was wating to buy N900 but, reading your post, I understood that perhaps is not the device right for me .
I tried a lot of Nokia device in the past but all had the same problem: a sync nigthmare due to bad quality of PC Suite. Unfortunately PC Suite seems more a basic home facility than a real way to sync device to your PC.

I think that N900 is a great device but is difficult to live inside it I need to interoperate with a full PIM software
