By way of owning a tablet, I am really enjoying my iPad. Its like a laptop in a way, but so portable and fast. Just click, on... Click again, at SOH, online, looking at a webpage. That instant. No booting up. Just 'crickie crickie' and you are doing what you want.
It makes you think... Shouldnt computers, as powerful as they are, be this fast by now?
Have you ever tried Linux? Most distros out there are small enough to fit on a CD or flash drive, and if you boot from the drive, you can play around in the OS without having to make any permanent changes to your system.
