i realize that.
but i don't wanna skype via UMTS/DSL or whatever, i wanna use this via the usual cell-phone network O.o
It seems me that
UMTS IS a cell-phone protocol; also would a lap-top be much better than a cell-phone?
Just think about it, when you turn on a cell-phone it takes some times to initialize and boot its OS, just like a lap-top would, but being the cell-phone porpouse to make calls and little else (the reason because the other functionalities are samwhat crappy is because they want to implement them without compromising the selling points of the cell-phone, very smal size and fast interface optimized for making calls (some models are not opimized, I loath cell-phones with all those icons to scroll trought or those pseudo-computer keybord so small that it's an issue to push the right key and not other three) which prevents the development of a proper interface for more complex functions), while the computer porpouse is to proces and store datas; the main barrier is interface, the interface for an optimal interaction with a computer reqiuires two things an input and an output, the output is the screen and the audio, the input for complex interaction is the keybord and the mouse/touch pad/touch sceen; as shown in a link in this thread the output is little as a problem, but the same can't be said for the input as ther is a size below wich keys are hard to be pushed, slowing down the tiping. Now this is (along the technological difficulties) the reason because laptops and cell-phones have developed as two different type of devices, making a call doesn't require much tiping while it is required to be easily accessible and transportable (smal interface), while complex interaction requires easy insertion of command and larger display, so larger intup-output.
Due the interface barrier (particulary for the input) lap-tops will continue to be too big to fit into a pocket (and cell-phones will keep being crappy as computer substitute), also to function as a cell-phone a lap-top should be carried around turned on and would require a place to stop (walking while using it can be source of ... things to happen), it's not very patical.
If you mean to use it when you are working without having to use the phone you software can fix it just as well, the closest thing would be to have the lap-top have a slot for a SIM-card, you siglate a contract with a provider and slot the SIM in, install a software from the provider (that is run at the system boot and stands in background until called for) that manages the connection and operates the various protocls (a virtual cell-phone), it wouldn't be much different from using skype or whatnot, and it would require to have specific hardware for the SIM-card (substancialy buiding a cell-phone into the lap-top) increasing the costs for no real benefit.
What I don't get is: what's wrong in the software way of problem resolution? It's easier and cheaper to implement, mantain and update.
