If you are an experienced android user with a rooted NC and miss being able to long press on an input field and cut/paste (or you are becoming an experienced android user and want cut/paste) you might be interested in this keyboard:
SlideIt -- a swiping keyboard with predictive text and cut/paste keys.
Video demo here. The full pay version is currently on sale for half price (around $4 US instead of $8 US).
I use it in conjunction with LastPass which stores all my passwords securely. If I need to enter a password into an app, I switch out of the app into LastPass, go to the entry, long press, and copy the password to the clipboard. Then back to the app and use the 'paste' key on the SlideIT keyword to paste it in the right field. On most android devices you can long press on the input field and get a paste option. This doesn't currently work on the NC.
Also, the swiping as entry is pretty cool, but I think it makes more sense on smaller devices. Takes a bit to learn how to work it, although traditional hunt and peck works too (and you can switch the keyboard to pure touch to pick with the ABC slider if swiping is just not for you).
