bought a touchscree pc was hoping to be able to brush on the screen but need a pen that has software to make it pressure sensitive,

basically is there any digital pens i can use on my pc that will make it into a massive tablet?

The screen is made for those raspberry jam sausages of yours to smudge around on, not for drawing detailed artwork on. My best guess would be to get a stylus, as I don't think a product such as the one you desire exists. How would a regular touch screen register you hovering a digital pen about it? Depending on the size of the pc, I reckon drawing on it would be a bother regardless.

oh so no good then? its 23'' so bit of room with it

the problem is, you have purchase a touch screen pc thinking it would work as a wacom cintiq, but it has nothing to do with it, even if you buy a stylus, this will have no [ressure sensitivity, this "stylus" would simulate your finger in a more precise way, other than that it would have nothing to compare with a wacom tablet, these computers where not made to draw on the screen, theyre normal all in one computer with touch screen capabilities

will have to see if i can get money back some way even just sell it, is there any computers that would suit what im looking for hugo?

you can keep that computer and buy a wacom which depending on your options can be a cheap solution or a rather expensive one,

or you can get a tablet pc with wacom capabilities (not as good as a proper wacom and can be very expensive)
the following tablet pc's have wacom digitizers and pens

HP ---2760p, 2740p, 2730p

Fujitsu --- T901 &T731, T900 & T730, T5010 & T4410

Lenovo --- X220t, X201t, X200t

Asus --- Eee Slate EP121

although i would advise keeping that pc since you spent money on it already and buy a wacom, a bamboo (now called intuos pen) is a cheap yet good wacom tablet, but if you can spend a little more i recommend the intuos 5 (now called intuos pro)

intuos Pen - £49.99 - http://www.wacom.com/gb/en/creative/intuos-pen

intuos pro - small - £199.90 - http://www.wacom.com/gb/en/creative/intuos-pro-s

medium - £329.99 - http://www.wacom.com/gb/en/creative/intuos-pro-m

i own the intuos pro M and it is by far the best wacom i have ever tested, i have owned several bamboos, intuos 3 M and intuos 4 L, and i am completely happy with the pro M. but the intuos pen (bamboo) is also a very nice tablet, better then any touch all in one pc will ever be

hope this helps

i think your right, i'l keep the pc i have, i have an old bamboo there which was handy will dig it out and see how it goes, would love something like the cintiq where you draw straight onto the screen but looking at the prices i would only buy it if i ever made money from photoshopping, thanks for all the help guys.
