There are alternative browsers you can run on Chromebooks. But I actually PREFER Chrome. The major negatives are not a lot of storage (Though you can plug in gigs of MicroSD card) and limited aps. though I find most of what I need they run. ONE program I have needs doze. but I can do everything else on Chromebook.
One big advantage.. i've had Chromebooks attacked by mal-ware.. Remove SD card. and very quickly get to Settings, Advanced, power wash, and your Chrome book is now brand new again, Same as when you first unwrapped it. Malware GONE. (unless it infected the card)
