Rumor has it that all of Chromebook's short life span issues will be addressed by ChromeReady, giving Chromebooks life spans similar to Linux machines.
Still, you will have to convert your Chromebook to CloudReady when the time comes ........ the same CloudReady can also convert your old dated Windows machine into a Chromebook just as easily.
CloudReady skips booting the machine to an OS and then separately having to go on line with a separate browser --- you just skip directly to the Chromium browser. Google bought CloudReady and is incorporating CloudReady's tricks into their own Chrome Browser Software.

Downside here is if you have a piece of old style program that has to run from Windows you may have to get an on-line version of that software or find a Linux program that picks up and writes back to the old format you are using.
Another good trick to remember is to use Libre Office software (Libre Office software has Linux, Windows and Mac versions available) People keep forgetting that Libre Office reads and writes all the old MS formats, so if you are caught out in this old version situation you should try Libre Office to see if it can open up your old MS format and let you see your data again.
If Libre Office software can open it, it can write back into any of the old MS formats, and you also have a chance to change the extension type to whatever the current MS standard you need for it to be. You can also reset the defaults in Libre Office to open up old stuff and then save your files automatically into the newer format that your end user can read.
I set this auto open auto save stuff up for my wife while she was still working, and she got a lot of kudos from her instructor buddies as Windows would abruptly stop supporting old file formats that had important teaching stuff in them, but Nancy could open the old file and then save it back in the more modern extension type and thus save all the work folks had invested over the years. This was much appreciated by her peers.
I'd find my wife sitting at my machine jest a chunkn' away at saving somebody else's butt time and again.
