I do all the time, I think it has a lot to do with the fact that the computer is how I learned
First here for the basic knit and purl (and I am surprised that they still work after the number of times I replayed them!)
Then, right after I learned those two stitches, I made Silvers socks and needed to follow each each stitch and had to have the pattern on the screen for weeks. I think it's more habit now than anything else, but I like (and would rather) to have the pattern on the screen rather than printed.
I Wish the FT clogs could be have been downloaded rather than printed on that awful blue colored card stock. That is part of the reason mine still aren't finished :( With the problems I have been having with my eyes, it's really hard for me to read the pattern.
Sorry for the novel, I seem to be getting carried away a lot lately here.
