I didn't have the time to read all 31 pages, but I wonder if anyone took a bigger leap than me - my previous phone was a Nokia 6820 .... produced 2003 I think.

I actually still use it now as I have multiple sim cards and I am still too paranoid to take my n900 out to some places, plus it's the best keyboard I ever used
