my 7650 from 2003 (soon nine years and counting...) still works.
a few highlights...

• first Nokia smartphone with the Symbian OS
• (version 6.1)
• first Series 60 (Now S60)) platform device
• first Nokia with built-in camera
• The handset's release was promoted in conjunction with the film Minority Report.
• it was also featured in Tom Raider 2...

i don't use it actively anymore (headset connector doesn't work properly (design fault) and is very heavy for the features it has)
