Re: Fanless laptop with backlit keyboard
For a bunch of people who think they're smart, the engineers and marketing execs in the computer industry sure are missing what is a glaring opportunity. Instead of using the new low power consumption processors to make fanless laptops, they have limited their market to more powerful tablets. They are completely ignoring a huge market: end users who want quiet, fanless, fully functional laptops.
Whom ever catches on, and uses the 8th gen intel, or Ryzen 7 processors to produce a fanless machine, with a 15 INCH SCREEN, backlit keyboard, and multiple usb ports, will corner the market and make a fortune.
All it takes is a simple google search for 'fanless laptop' to realize how many end users are searching for a traditional laptop that is fanless, and silent. We have tablets for extreme mobility, and that's great. What we're looking for is a fanless desktop replacement. Clearly, the technology exists to produce them. Engineers and execs need to open their eyes and realize that the market is craving this kind of machine."
