The problem with Chrome, and Mozilla "book" when it comes out for that matter, is the same problem the Amiga from Commodore had back in the 80's.
I was there when the first PC was released (That is my memory goes back that far) at the time the little Commodore 64 I had was far better than the 8088 based PC, so was teh TI- home computer, and the MAC (Though the price of the mac was kind of high). and the best of the lot was the Amiga.. NOTHING then could come close to the abilities of the Amiga and in fact today.. It would still be a contender in the market. (Took windows quite a while to catch up with the Commodore 64 for that matter.. but we won't bother with that).
PC was from IBM.. and many companies, even though the machine was made by honeywell or Burroughs,, called the computer room the IBM room.
Thus software developers jumped on the Poor Computer right left and center, abandoning the better comptuers to the junk heap.
Enough history
The problem with Chrome or Mozilla OS is this: There is little software out there for it.. So if all you want is a Web and E-mail client.. They are great.
But if you want to control your Ham Radio,,, (Ham Radio Delux) or read the operation of your engine (Assorted OBD II products) or do most anything other than browse the web.
no joy.
