If like me you have some old hardware lying around and you want a way to make it useful again there are some options. In my case I have an Acer Aspire One ZG5 netbook I bought a number years ago. It is capable of running Linux but the screen resolution is far to low and with a maximum of 1.5GB of RAM Linux isn't going to provide the best experience. For this reason I chose to try out Chromium, the open source version of Chrome OS. Chromium is open source and because of this you will find many different variations just like you do wit Linux. I chose to try "ArnoldTheBat's special build of Chromium OS". This is a recent build as of May 21st, 2016, unlike some that haven't been updated for years. You can find all of the downloads here with the most recent and older versions alike. Your mileage may vary depending on the hardware you are using. If you are using an Acer Aspire One ZG5 netbook then yo are in luck.
If you are interested in trying a supported version of chromium with driver updates etc..... then you can give CloudReady by Neverware a try, it can be found here. Keep in mind this is pay ware and will require you to purchase a license unless you want to take the self support route.
If you want to give Arnold the Bat's distro a try then continue on below.
FYI, you will be prompted for an e-mail address to login to Chromium.
Install instructions were found on the blog: http://sakarinkurssit.blogspot.fi/2014/12/arnoldthebats-special-build-of-chromium.html
Prepare your USB stick and boot PC from USB
Basic Netbook Hardware:
CPU: Intel Atom N270 1.6GHz CPU
Hard Drive: 120GB
Built-in Screen: 1024x600
Chromium on my aging netbook with a single core hyper threaded Atom processor has breathed new life into my aging hardware. The OS is responsive and provides additional functionality through applications that can be installed from the included web store. As expected when loading complicated web pages there is a slight delay because of the slower hardware in my netbook. When scrolling through the web pages the netbook does a good job keeping up with the pages.
Based on my usage of this distribution I did not find an option to support tap clicking. Installing applications is relatively painless reasonable number of available applications. The netbook heats up quite a bit causing the fans to spin constantly so the netbook won't last long on battery.
In conclusion I would recommend giving Chromium OS a try if for no other reason than to satisfy a curiosity. Chromium OS does provide good performance for basic functions allowing you to extend older hardware's usefulness. If you have a notebook with better class hardware your experience will be improved over mine.
