Question about Microsoft Surface Pro 7

Have an HP pen... works perfectly but erasing with the Microsoft pen is of course more comfortable as it has a rubber cap on the opposite end of the tip. This works more or less like a real eraser.

Theoretically, Windows 10 Home needs about 20GB of memory. I have also installed a 256GB SD card to store photos, music and videos. The internal memory remains free for programmes etc. and is sufficient for my applications (I have Win Pro installed). The device is absolutely top and fun to use, also because of the ingenious functions with the pen.
