There were technicians long before phones, I'm sure many of them would say their lives were great.
I'm still not planning to give up my phone though. I like having tracking on my keys and being able to add stuff to my shopping list without stopping, and no longer being constantly lost everywhere I go.
Not for me. I don't even own a smartphone, just a good old small mobile phone whose battery charge virtually lasts forever. I can't do anything useful with a computer that doesn't have a proper keyboard and screen.
Snoop-phone's screens are very good nowadays, to be honest.
I'm actually more interested in the possibility to used such phones as a mobile internet access point. The Nokia I'm using can connect by WLAN or USB to my laptop, which is great.
I consider a full techy life to include creating tech, so I maximise my device time for those with keyboards, and minimise for those without.
For me, creating tech very often starts on a phone, as a random note that probably sits there for months as a "Wouldn't that be cool" project, before I collect enough of the pieces of research to actually start.
