this pen phone can be had for ~$40 USD.
Cheating on exams 10 years ago?
Yes but can it run DOOM?
Idk but there is a really cool pen that stores your notes as you write them.
You just unlocked deeply buried memories of that Leapfrog Pentop Computer thing from the mid 2000s. I can’t remember if I actually owned one or just got to use one, but I remember being captivated by it. Apparently the guy who developed it went on to found Lightscribe (which produces the pen you’re probably talking about).
None. But id buy it just for fun and so i can fill up some landfill space which we apparently have unlimited of so
