I worked on the Big Iron (mainframes) in the 1980s as a mainframe operator and systems programmer. I moved to PCs and servers in the 90s. In the Naughties I became a citizen of Laptop Nation. Each step enabled me to be more free and more mobile and to access more "stuff": multimedia, Internet.....anything digital.
Now? I'm Mobile Man. If the device can't transmit, I don't want it. Dead weight. Why would I want a camera that can't instantly send images to wherever? Or a PC I can't just put in my shirt pocket?
I gave away my laptop over a year ago to my uni-engaged daughter. My main computer, camera (still & video), stereo (nice old word), comms device of all types (email, txt, FB, Twitter, phone), is my (multi-tasking, access any data anywhere, any time) Android smart phone.
The last bastions of PC required-ness are the touch-type keyboard for lots of words in a short space of time; playing big games on a big screen; and video editing....and even then it's a close-run thing on all counts.
The SlideIt "swipe" soft keyboard I got from the Android Market for lunch money allows me to quickly type a lot of words very accurately by just swiping my finger around the screen. I'm writing longer and longer things this way.
My phone has an HDMI out port, so if I had an HDMI TV ( I don't - my bad), I could already be playing phone games on a huge screen.
For video editing. "Vid-Trim Pro" lets me me basic selection of the chunks of video I want. Usually thats all I need anyway. The PC still does the heavy lifting.
But on all counts....I can see the day very soon when a large screen phone or phone / tablet / netbook device will do it all.
When I get my hands on one of those, I'll be Liberated Super Mobile Man. If you get on that bus first, save me a seat. I won't be long.
