I'm considering purchasing a tablet with no screen that connects to your monitor. Questions like this explained that this is no problem because after all, you don't need to look at your mousepad to draw with a mouse. But a mouse stops drawing when you stop clicking. How do you keep your pen from drawing a pencil mark when you touch it to the pad to find out where the cursor is?
You don't need to touch the pen to the tablet to see where the cursor is. Touching the pad will always draw but you can move the cursor around by hovering your pen just above (without actually touching) the tablet.
Honestly it is no problem at all and once you get used to it you can use it instead of a mouse completely. I know people who will use it for normal everyday use like browsing the Internet, checking emails, everything.
