I have a Acer Chromebook that I got from BestBuy for $57 bucks (after using a gift card) and it is wonderful for anything web related. You can even use SSH on it via a Chrome Extension to access other machines. With programing in the web-browser, to remote access via ssh or logmein, most things can be done using a Chromebook.
I started to use mine as a loaner when fixing peoples computers, and what I found surprising is that most people, especially older folk, whom struggle with using a computer, love that it just works to get online, is fast, nothing to worry about security and infections, and is perfect for someone on the go or traveling.
My only complaint is lack of being able to access network drives with the file manager. Google please fix this! My NAS supports SMB/Cliff, AFP, Bonjour, and NFS, yet the file manager only see local files. Being Linux, you would think that it would, at least, have NFS support.
