Some of my friends said that tablet PCs are useless, is that true? are they good?does alot of people buy them?

Answer 1

That's really a very biased statement.
Useless to whom ?
It depends on your needs.

In the business & academic world they are enormously usefull & popular.
To a young gamer they offer no attractive features whatsoever.
To a student in higher educaion & in the business world they offer features that prove convenient & timesaving.

Answer 2

Yes, your friends are correct.

* Higher cost — convertible tablet PCs cost roughly $300 more than their non-tablet counterparts as of 2005. This premium is expected to fall to as low as $75 by 2007.However, some models are intentionally priced at the same point or lower than equivalent notebooks without tablet functionality.
* Screen size — the size of tablet PC screens currently peaks at 14.1 inches. However, some models make up for this with very high resolution (a higher pixel density per unit area). The main problem is the size of people's pockets - where the Tablet PC is kept.
* Digitizer issues — some tablet digitizers cannot keep up if the user writes or draws too quickly, reducing the fluidity of the lines the computer captures. In addition, the signal from the pen may become distorted near the edges of the screen.
* Input speed — maximum handwriting speed can be significantly slower than maximum typing speed, which can be as high as 50-150 WPM.
* Screen damage risk - Because Tablet PC's are handled more than conventional laptops yet built on the frames of conventional notebooks, and because their screens also serve as input devices, many Tablet PC's run a higher risk of screen damage. PDAs carry some of the same risk.
* No Built in Optical Drive in most Tablet PC's — That is because Tablet PC's are handheld and so they have to have a small mass

I don't think that Tablet PC's are useless. A lot of people buy them, and they can be useful in different occasions.
