These days, many devices are "converging". There is nothing new about it. Everyone will tell you that in a few years time, you will be able to buy a mobile phone that is also an FM radio, digital camera, PDA, MP3 player, universal remote control, USB drive, clock, have untold wireless connectivity protocols, and computer (with web browser, email & other general computer abilities).

Many experts would hesitate to include the "computer" in the above list. They mention many technical difficulties, such as: screen resolution, keyboard, pointing device (mouse), processor speed, heat dissipation & battery life.

I argue that Similar arguments can be made about laptop/notebook PCs. Take a look at many offices today, & you will see many laptops being used as a normal desktop computer. People will connect external mice, keyboards & monitors & then you hardly notice you are using a laptop.

Now, you are also seeing many wireless keyboards & mice... All that is missing are wireless monitors. The reason that there are no wireless monitors is most likely because there are no wireless protocols that can handle the sheer volume of information that is sent to monitors.

Once wireless monitors become feasible, the paradigm shift to using your mobile phone as you PC is very easy to make.

In fact, your mobile phone will truly embody the meaning of the word "PERSONAL computer": you take it with you wherever you go. While using the built-in screen will give you limited PC functionality, as soon as you walk into your office or home, place the phone near the wireless screen/keyboard/mouse, and press the "synchronise" button on these devices, and they will automatically become extensions of your phone.

You can surf the internet, read emails, & play games using your phone as the computer, except a hi-resolution screen & a full keyboard & mouse will make it much easier to do what you want.

As far as I can see, the major piece in the puzzle that is missing, is the ability to connect a mobile to a monitor (regardless of whether the monitor is "wireless")

All the building blocks for this scenario are almost in place, so the next few years should be quite interesting.
