Vogue-
I’m afraid I know nothing about chromebooks.
Some really quick research on the $249 Samsung Chromebook shows:
-It’s not a PC at all. It isn’t even comparable to a PC. It uses its own operating system, and it’s primarily intended to be used with both apps and data residing on the web. (It can be used while offline, too.)
-It gets good reviews from technical sites.
-It seems quite capable of handling your requirements.
I strongly recommend that you read reviews – both professional and man-on-the-street – to help decide if this is something you’re interested in. Even better would be if you can get your hands on one (perhaps a friend’s?) to try things out for yourself.
Also, if you will be accessing documents you create on your Chromebook from a different machine, will there be any compatibility or conversion issues?
Wish I could be more helpful.
