Lol! First they upgraded regular phones into tiny computers, which is great because who can live without their smartphones nowadays, right? But do we really need to take the pen on the same path? I mean, it looks really cool. Like @conradt said, it's something that looks like James Bond himself would use. But for everyday people, do we really need something like that?
Personally, I'm concerned that I'll break it if I use it as my everyday pen. My pen gets a lot abuse, you know. I drop it a lot, sometimes I even bang it on the table, if I'm frustrated by what I'm writing. It's just not practical to turn something like a pen into a sophisticated device like what they're trying to do. Unless of course, they don't really care about the pen as a writing instrument, which I think is the case here. So, no. I'll buy an everyday pen and get a USB for my smartphone, instead.
