I doubt the Chromebook was ever designed for people like us. We demand far more from our technology and multitask in ways the average user simply doesn't. My Android tablet is nice, but I can't even open up 10+ new tabs at once on a whim and let them all load in the background without it dying.
And forget having them all loaded where I left them when I next return to Chrome.
A friend of mine once put it that if you're the kind of person that thinks a Chromebook is neat, you're not the target market for a Chromebook. I think you and he are both right. The only reason I even attempted it is because I damaged my Series 9 so much that it wouldn't start, so for a few months I just used what I had.
