ThinkPad X201 Tablet upgrade/change to Multitouch screen?

[inawarminister]

Good day,
I've just bought a secondhand X201 Tablet, and, well, it's my own fault but I didn't notice that this model has no finger touch, only stylus.
I mean, I like using the stylus, it's just that Windows 8 is designed for finger multitouch, and since it should be available...
I've searched around the net and it seems there is someone who's looking on the changing (in his case broken) screen to the multitouch capacitive versions Samsung LTN121AP0310 or Toshiba LTD121KX6B.

I'm a noob, so sorry if this violate forum etiquette or anything, but is there an easy to follow guide for laymen like me?
Thank you,
inawarminister.
