I had a sony ericsson walkman phone which had an app store. I installed a nice chat application which let me chat on Google talk and facebook. It's email client was pretty decent (for the time), it ran Opera mini, and it also had a twitter client. I guess that was smart enough to be called a smart phone. The phone was also about a centimeter thick, and in that time (probably even for now), it was sleek and beautiful. I miss that phone.
