portable computers

PDA's and laptops are becoming the computer of choice for the young and old alike. PDA's are hand sized information storage units that also serve as phones, music players and notebooks/memo recorders. Laptops make it easy to move your computer needs around your own home without rearranging the furniture. In addition to home flexibility these computers can leave the home with the user and continue to operate and date storage units and pick up signals to access the internet for communications and messaging. I wonder how long before we don a small thin layered helmet with a small lense/screen for us to operate a computer.
