I’ve been having this disrupting ideas for for years, and it seems that every year I (sadly) get one more:

• actually open source software all the way down to the kernel and drivers.
• user replaceable batteries.
• micro SD slot.
• 3.5mm audio jack.
• zero glue.
• free schematics.
• parts available for purchase.

Does the phone costs double? I don’t care. Shut up and take my money!
