I'd like to see an E ink display on the back or on the case as an option on their crowdfunding venture or else a case with kickstand.

No actually I'd like the HTC One to get a good sailfish port if this phone is going to be low high end.

How about an app that when you clap twice the phone can vibrate across the table towards your voice?

There are different sizes of people with different sized hands. Do you really think it is fair to ask a basketball player that is almost 7 feet tall to use the N9 screen? He's going to want a 5 incher.
I'm 6'1" so I want a maybe a 4.5 or 4.3 something like that.

But regardless I think the sailfish OS kind of needs a large screen in order to make proper one handed use of the "covers" or multitasking UI.
