I think all of computing will eventually go this direction because of all the spyware and viruses out there.
I currently run Puppy Linux distro from CD which boots into ram memory only and then can save everything back to CD-R with Multi-session.
I beleive one day you will be able to walk up to any computer and insert your Credit card sized CD-R disk or usb keychain drive, with your chosen OS and all your files on it and boot up, Compute then when you are done save your files back to disk or drive. After all small drives and disks are almost at the size of Hard drives years ago and cheap.
As far as security I think it is a multi-layered approach and will eventually be tied to both a hardward token or usb pen or keychain drive and a PIN number or password together.
