When a product is better than the description

When I was a kid I liked wrist watches from Casio. I had one with a calculator, one with an address database, one with an infrared remote control and one with an altimeter. But for the last 25 years I didn’t wear one. I don’t like to wrap anything around my wrist. And since I […]

After playing with it for a while the excitement turned into dissatisfaction. I hate to say it, but on a phone the solid base and polished user experience is not enough, […]

The key to the performance lies in the parallel architecture of these devices. From what I read, […]
