Google

Google offers so many great things... The more I use their applications, the more I find other things they've already thought of.  It feels like there has to be a catch, but I don't think there is.  A friend of mine was recently telling me about Google Voice and... it just seems to offer all the things that you might imagine the phone of the future to have.  Going somewhere? Forward the number.  Walking down the street but want to screen the incoming call?  Done.  Going off shift and want to forward your number to work/office? Done.  Screen particular calls?  Forward work only calls but keep personal calls coming to the cell??  Wow.
I think slowly this will move us all towards (or return to, in some ways) simply using a terminal that connects us to ... google.  In some ways, it's better: your data is probably safer, likely backed up multiple times (I'd wager 90% of you don't really regularly back up your data.. maybe some really important things you want to be sure to keep, but everything?) Then, accessing all of your "desktop" is basically just through connecting, with no reliance on a single computer.  I have a decent portion of this already, and it's really amazing.  I can open at work, access all my documents, close, and re-open at home, or an internet cafe, or on my phone! 
Some of you may have realized all of this already.  I once was a young man, playing with FidoNet, BBS's, and 300bps modems.  Somewhere in the middle, I slowed down to pursue other things; but to stand back occasionally and look at what we are capable of now compared to those days... it is really something.
