I have been studying the Magic Leap One (ML1) for a few weeks, taking over 1,000 photos and making many measurements. I’m bursting with things I want to talk about, so I am planning to releas…
I don’t own an Apple Watch. I do have a Fitbit. But the Apple Watch 4 announcement intrigued me in a way no other product has since the original IPhone. This wasn’t just another product announcemen…
I have a love-hate relationship with ad blockers. On the one hand, I despise the obnoxious ads that are forced down our throats at what seems like every turn. On the other hand, I appreciate the need for publishers to earn a living so that I can consume their
