It's been over three years now and I'm hoping to stick with it for some time to come!

... resistive screen + MyPaint make it fabulous for drawing ...
... MicroB browser for real desktop browsing instead of the cripped mobile sites ...
... FM transmitter for all my music on the go ...
... and a real ( if very scuffed!) keyboard for fast accurate typing! ...
... intergrated Skype, IM & IRC mean it will still be a great phone even if I move my sim onto something else ...

... until I find another phone with all those attributes this will be the smart phone for me ... unfortunately the manufacturers all seem to have a different idea about what makes a good phone these days ...
