Re: Windows 10 - so what?
@ Gary_EL "I fail to see how the advent of Windows 10 will do anything to enhance PC sales."
Couldn't we say the same about new cars, new phones, the latest trend in clothing, etc?
"they are no longer sold with any way to reinstall the operating system"
I know it's not the same, but there are several ways to reinstall an OS without the media. On Windows 10 for instance, you can do it from Recovery or if you're on it, from Settings/Reset this PC. You could also download the media creation tool for Win 10, and create an USB, DVD or an ISO.
"Anyone who needs a larger screen, or needs to look at two things at once will need a PC."
Not necessarily. You could plug a secondary monitor on the laptop's VGA port, or the HDMI port. You could even get a beautiful 16", USB Portable Monitor. Not very expensive nowadays.
I forgot to mention that you could also add a tablet as a second monitor. I did it a couple of times with my phone. Well, as you can imagine, the screen was rather small, but with a 10" tablet, it might work just fine.
So you see, a laptop can have up to 4 extra monitors. That will be a nice setup. Now, if I only have $1000...
"Well, more than a niche"
I hope you're right, or I feel a bit isolated
