There is no longer a shirt clip, for example, which some people won't like.

With the new Surface Pen, the IAF is down to around nine grams, making it more sensitive than the last version.īesides the big technical changes with the new Surface Pen, there are subtle physical changes as well. A similar real-world analogy is how a Sharpie marker can lightly brush against an object and leave a mark versus a pencil. Initial activation force (IAF) refers to the amount of pressure needed for a pen to trigger an inking event on the PC – the lower, the better. The new Surface Pen supports this feature, as well, thanks to advanced hardware. too, but simulating it on a PC is not easy – after all, it's just plastic on glass and the computer does not "know" the difference. If you took a real pencil and turned the tip on its side you could use it to "shade." That fanning of the graphite creates a different experience than just writing with the tip.
