I send about 1 message (sms) per week. I really have no need. All my friends have push email or instant messaging on their phone. So I send hundreds of emails a day (or IMs) and make about 1 phone call a day. I'm very data intensive. I think the N900 will make a great "always on" companion! But I would like to have some portrait pages (like calendar, messages and web browsing) as many times I'm walking and I just take a look at the phone to check to see if I have messages even though I have no interest in answering. Or I'm walking and I want to see where I have to go, or verify a time. Other than that, as long as the phone part keeps a stable connection, and receives calls and SMS I'm happy
