No, sorry, at least not for the Kpw1 -
Due to the system implementation done by lab126, you can get at least six touches ahead of the processing, without even trying.
There is plenty of computer resources "under the hood" of either of the K5 models, just mostly being wasted.
Well, I will back off a bit on that - -
They set out to build an e-book reader, not a general purpose computer system.
And build an e-book reader they did.
If it has some failings as a general purpose computer system, well, "it wasn't in the job specs."
As a hint of what is 'under the hood' take a look at some of the compute intensive tasks being done here on Kindles -
Speaker independent, voice recognition and control -
Running IBM's mainframe VM/370 operating system, **under emulation**, with reasonable single session response -
A lot of the media processing (video and audio) being done on the Kindle.
So, yeah, it **could** have been designed to keep up with the fastest typist, but it wasn't.
