I am very bad at keeping my stuff safe while traveling. I traveled 2 to 3 times every year. I lost my bag with my laptop in it 3 times in the last 5 years. I do not want to bring my regular laptop with me anymore in my next travel. I am thinking of getting a cheap refurbished Chromebook. I mostly only watch movies from USB key or YouTube, check emails, and browse the web while traveling. Only in a very urgent situation ( 2 times in the last 5 years) I had to log into my bank accounts. Some cheap refurbished Chromebooks can go as low as under $100 and they should be able to do the job. However, these cheaper ones are too old to get any more updates. I assume that they will still run. Unsupported Chromebooks are not getting system updates. I can run Android apps on the Chromebook. If I run Firefox browser app and anti-virus app, will updates of apps running on it cover some of the loopholes left by missing system patches?
