Hi,

I am looking to get out of windows, but since I last checked there was no mobile device that could sync contact/calendar/files/tasks with thunderbird (or similar program,) without putting all the info into google's cloud.

Right now I am using Palm Treo Pro with windows and outlook (total drag.) However there are features that I can't do without: qwerty keyboard, 3.5mm jack, spreadsheets/calendar/contacts/tasks/office, and it syncs with outlook (I am not at all attached to outlook and would prefer and open source version like thundirbird).

Is there an option out there in the open source world (without the cloud) with these features? I'm hoping to stay under 200$ (for the phone device), but I would look into anything if necessary. Also I need something pretty easy to use because I am not very tech savy. Also I am not going to hook up the phone to tower connection, and don’t use wireless in my house, so the sync has to happen over USB.
Do you think the N900 is the answer? Are there any other solutions that are more up to date? Also, can the N900 run android apps?

Thanks!
