but a bit different. when just "hanging out" on my PC I have music playing, surf multiple web sites, play games, whatever.
I wouldn't do a single one on a tiny phone. I have a Palm Treo that work gave me, I hate using it. The tiny screen, and totally un-usable keyboard is a waste of equipment to me. The only think I do on it is get email and phone calls. If I get an email I need to respond to I fire up the laptop, VPN in and respond. Now granted I don't have a lifestyle where I am out and about and need to "work", and I hope to God I never do. If I am at the beach I am not working. there is a reason for that.
oh yeah, I need a new phone for myself. ALL I care it does is have great reception wherever I want it, a good alarm, a loud ringer, long battery life, as small as possible to fit in my pocket, and NOT a flip open thing. that's it. I do not / will not use it for any function other than making and receiving telephone calls. I don't know any kids I need to text, I don't need a camera to take pictures or videos of street fighting bums, I don't even need a color display. my old Nokia was the BEST phone ever, and did all listed above with a monochrome screen.
Another issue is the phone not being able to do the things I'd want. If I want to play a game it is going to be AH or something PC intensive.
I think there is going to be a separation of 2 different types of people, those
"on the go" and those not. Those on the go will have devices that do amazing things, and those people will use it for everything. Those not will do completely different activities on PC's and the PC culture will differentiate from the on the go's.
