Re: Calls and Email
Most email CLIENTS send plain text as well as the embroidered crap. Most of the actual content is in the plain text anyway.
The exception to this is automated responders by big companies (ebay/amazon/paypal etc) who often send empty 'text/plain' sections. Which is user hostile.
But personal emails even from a high up mangler, will usually have usable content in the text/plain area
