I figure none of them had tilt, but I can’t underatand why new EMR has it and old ones didn’t. What’s changed? Is it something in board or the pen? If it’s in the pen, why can’t we have tilt on older EMR tech? Is it software? Etc. And yes there’s something about the built in matte screen protectors that’s clearly better to write on, than one we install. Something different about the Sp itself. ?
