My wishlist consists exactly of one item:
a phone with ordinary phone keyboard (like old good feature phones), but with good hardware inside and a free software.
I hate touchscreens (pecking the screen with greasy fingers? No feedback from the input device? Gosh…) and believe that it is not necessary to give up the keyboard in favor of touch screen, if you want to have a good hardware inside the phone. This approach just needs more elaboration from UX perspective. Some fruits here are low-hanging, e.g. adding WiFi module to the keyboarded phone should not be so hard.
The real problem in the current market of keyboarded phones is that there are few models which have some good hardware stuff inside (WiFi, GPS, good camera, etc.), but they are completely proprietary (without any possibility to install/remove/tune the software), and the OOB software is a complete crap, making good hardware useless (the real example - a browser, which both does not allow ignoring the certificates it does not trust to by default, and have no means to install new root CA certs. This makes surfing effectively useless despite the fact that it is possible from hardware perspective).
