Isn't a Chromebook just limited to web browsing? iPads can do that and more, right?
Also, many people I know with $1000+ MacBooks use them for almost nothing but web browsing.

I often run into situations where I literally cannot have just 2 tabs open in Safari and switch between them without losing everything I've typed into text fields since it runs out of memory and dumps the other tab.
I bought an iPad 2 on release, and still use it to this day. I've literally never run into the problem that you describe, and for a few months I did all of my work on it.
