Not that "High-PPI" is all that useful of a term either, any more than "Ultra High Frequency" or "Very High Frequency" or "Super High Frequency".

High PPI is the literal description of the phenomena referred to by the OP. Its not a buzzword or a trademark, its a technical specification.

326 PPI is a technical specification. "High PPI" is a buzzword used to sell things - our current use of it will be invalid in a few years.

edit: deleted first sentence, was more off-topic than useful.

I don't think we need terms like "retina" or "high PPI" at all. Consumers can decide which PPI is good enough for themselves.

Sharp is now producing 5-inch 1920x1080 443 PPI displays. Obviously this is much higher than anything we have ever seen, so it is not a "retina display". What should we call it? Instead of "cornea display" or "very high PPI", I prefer the term "443 PPI".

given that apple's retina and android's xhdpi spec fall into the same number's it's still fair to use the phrase 'high dpi'
