I still wish I’d kept my W910i. Unreliable software that would reboot randomly, but a surprisingly sturdy piece of kit that survived many drops and skids. And it was the best camera I had for a while, delivering a wonderful 2MP.
Then they were supplanted by early non-Android Samsung phones with the bad touchscreens, then by 2012 everyone had either an iPhone or Android.
It was only the space of a few years but seemed much longer back then!
Funny that a few years before that I was a big Palm/Clie enthousiaste, so the idea of "all screen no keyboard" wasn't new to me. Yet I gave up after Tungsten T5 and stayed with just Sony Ericssons for several years with no desire to but a PDA or smartphone.
I miss the jog-dial ones. At least, I remember it very fondly but I would probably hate it now.
