Tablets are fine for the folk that want some multimedia, email, and surfing. Tablets will continue to evolve in this market. Power users will continue with desktops and laptops. The pro version of the Windows 8 tablet will offer portability for high end users and will be a step on the road to replacing the desktop pc.
The real revolution will occur when the majority have high speed internet access and the cloud becomes a valuable alternative to local storage and we will see hybrid tablet systems with large screen docking systems. There will have to be changes in hardware with battery life, screens, processing power, storage and memory to facilitate this revolution.
We are at the beginning of a long road which will bring the integration of the desktop, laptops, netbooks tablets and communication devices. It's a journey that I am looking forward to. What great times ahead!
