I'm reading much about the need to input numbers, but what about text browsing and edition? Do you, tenkeyless and full 100% users, use your numpad or the central block to position your cursor when programming or editing texts? For me it's much easier, comfortable and intuitive to use the numpad cursors and not to have to move my hand to reach the end, home, pgdn and pgup, just to go to the end of the line, the beginning and scroll the text up and down. I couldn't get use to do it with the central block. Actually, I think it would be as annoying as using FN + cursors, as happens with some 60% keyboards.
