They can. I know that HP makes a desktop with touch screen. There are also laptops that allow you to write on the screen as if it were a piece of paper. Limits in operating systems have a lot to do with why we don’t see more of this. Plus there is not a huge demand for that yet. Windows 7 will allow that technology to develop a lot more as they have put special features in it for touch screen technology.
it’s because of two main problems with laptops
price and power
the touchscreen on your iphone is the most expensive part of the device and since it serves a dual purpose it also eats twice as much power as a typical screen.
on laptops, buyers prefer a longer lasting battery than the latest capability
in fact, compaq/hp had a Compaq Touch Screen Pen Tablet PC TC1000 Series in 2002. it didn’t catch on except in the medical field because nurses can just run up to doctor to get his signature and not worry about paper copies
interestingly, toshiba owns the patent for this idea. that might be another reason why all the other notebook manufacturers including apple are not in a rush to get one out yet.
would you like to see that your screen is full of fingerprint?
and there are always delay on touch screen,it is not convinient to operate the laptop.Moreover,is it necessary to design a touch screen laptop?I think using a mouse is convinient enough.Touch screen is designed for cellphone which is oprated by keyborad.
They can, and do. Not with the same features as them, (ie. two-finger spread zooming out), but there are touchscreen laptops.
HP has a tx2600ca series with touchscreen. The laptops themselves are more expensive, and not everyone needs them. Having said that, it’s pretty self-explanatory that not every single laptop has them.
you know it may sound crazy but i think that must of the computer screens can be used as a touch screen; the problem has to do with the programing need it for it (i know that fujitsu has the copyrights for that technology in fact they are using it for ticket bending and order taking machines now)
Yeah it is possible. There are so many laptops with touch screen as an iphone. I have seen different brands with it but the problem is they cost an arm and a leg. Most of users prefer to pay more on powerful configuration instead of touch screen thing!
then they wouldnt be called laptops
I presume you are referring to resistive and capacitive technologies in screens. Laptops (and many Windows Mobile) phones use resistive touchscreens which are less accurate and cheaper. The iPhone uses a capacitive screen – which has extra parts in it like the thick glass substrates, so I’d imagine most of the problem is cost and weight.
You also have to offset the loss in clarity of a touchscreen – the iPhone is fine because it’s small so you don’t notice so much and the screen itself is decent.
Finally, touchscreens are handy from time-to-time but I 100% guarantee you your arms and fingers would get tired after a whole day of using one if you had one at your desk at work.
