Tablet handwriting density

[Thinkerer]

I'm considering getting an X41 Tablet (or the X60 Tablet), with two primary use being note-taking during lectures and detailed annotation of documents. The form factor and ability to enter free-form diagrams and math seems very attractive. However, I wonder about the following:

How densely can you write using the stylus, while keeping the handwriting legible? And how small can the letters get without foiling handwriting recognition? Does the bottleneck lie with the digitizer accuracy, or the LCD resolution?

I'm attaching a poll for easy feedback, but would appreciate more details about experience (and screenshots would be great!).
