Linkbait article's dirty secret: actually some Android models have 30-40% return rate. Of course the article makes no attempt to estimate aggregate return rate rendering itself pretty meaningless.
I think this is mostly people getting what they paid for. I'm sure lots of people who bought Androids said "oh, well, it's just like an iPhone and everyone has those" but what they were actually thinking was "damn this is so much cheaper".
You get what you pay for. Case in point: spring for a Nexus. No problems.
FWIW I love my Captivate (Samsung Galaxy phone) and I paid less than $50. I wish they were better about updating the Android version, but I wouldn't say the Nexus is the only Android worth having.
UI replacements, vendor bloatware, slow updates and variable quality hardware. Stick with pure android devices, they are better. The iPhone is clean - no bloatware,etc. Demand the same from Android.
