Title: What cheap yet very useful things have made a substantial change and improvement to your life?<p>For me it has always been USB flash drives. I&#x27;m scared of getting ransomware&#x27;d one day, but I am safe in the knowledge that I&#x27;d have to have every thumbdrive I own plugged into my PC for some real damage to happen. They are a lifesaver, and they get cheaper every year too!
