No, it's not iPad, but the Always Infinity Sanitary Pad that is really revolutionary.
(OK, for those who don't need to use this kind of product, stop reading now.)
Years ago, Always introduced the "winged" design in their sanitary pad, that was quite a break through. (Anybody still remember the Sylvia Cheng commercial?) It's a small change in the design, but greatly improve the usability. After that, there were many small improvements. The pad became thinner, and the material became more absorbent, but they were just minor changes. But the new Always Infinity is different, the difference is a big WOW.
First of all, you immediately realized, this time, they really hired someone with fluid dynamics degree to design it. It's high tech. While looked not much different from the previous design, the new design directs all the liquid to the bottom of the pad and keeps the top dry. (Turn it and you will be amazed.) It also absorbs things fast, extremely fast. The texture of the top layer material also changed. The plastic like material is replaced by a more environmentally friendly material. It's more paper like and easier on the skin. (I wonder if the same technology may have already been used in making diapers.)
The whole experience makes me wonder. Which technology has more impact on my life? Which pad I am willing to give up, which one I can't live without? And the answer amuses me.
