Already I see due to the mobility required in my job I cannot work with a conventional desktop. At the same time I do much more than just checking emails and surfing. So I have to have a laptop that I can lug around, station at any place and work with it.

However there are times, such as waiting at airports, travelling and such when using the laptop is cumbersome and a tablet-like device would be welcome. Also sometimes I plan to catch up with some work late in the night at home, but after reaching home I just don't have the time to open the laptop, switch it on, wait till the booting is over, login and then wait yet again, and then finally start working. Instead if I had a device which powered on instantly and could occupy lesser space on the dining table, I could catch up with some work.

A convergence where there are tablets attached to docking stations and we can attach external peripherals such as keyboards, mice and pendrives would probably be the best.

My thought is more on the software front. There is no single OS on all the hardware that we seem to be running. Most popularly the office machines are running Windows. If you own any smartphones, you are using either Symbian, Bada, iOS, Android, WebOS or some such. Laptops could again be either Windows or Linux or Mac. With such a diverse software platform, there is a very small number of apps which can actually work across the platforms, specially when anything more serious than emails and surfing is planned.
