As promised. some first thoughts and experiences

Cover display:

• If an alarm goes off you cannot snooze or stop it from the cover display
• If you open the cosmo when the alarm goes off, it asks you for your PIN first to unlock the phone, then it pops to the home-screen, and the
  alarm is still ringing in the background.

=> It's uneasy to stop / snooze an alarm if the device is closed.
If the device is open when the alarm goes off, you can stop / snooze it normally on the internal display.

See: https://imgur.com/a/RxiNAls as an example for the lock screen and the alarm blazing in the background.

• The cover-display is laggy, entering a PIN to unlock the phone is a gruesome experience, as its animations are always 500ms to late.

Other oddities:

• If you turn on the keyboard backlight the devices shows the "charging" icon.
• Uneven lighting of keyboard and cover-display LEDs.
• The device is full of google-software. The searchbar on the homescreen can not be removed.
• When using the main screen, the device suddenly locks sometimes, and you need to enter your pin again.

Look an feel / Keyboard
The device feels really solid and typing on a real clicky keyboard again is a good thing. When using it in both hands, i can thumb-type on the keyboard, my girlfriend cannot.

Typing-speed.net results: Cosmo: 164 strokes/minute, Notebook: 244 strokes/minute, whilst cosmo was thumb-typing and notebook freestyle.


Music:

• This device can really get loud. Listening to music on the inbuilt stereo speakers is possible, but the audio quality is meh. Just use high quality headphones. Always.
• Cover Display can show the current played track when using a player like VLC, this is cool! Playback controls do also work, but are laggy.

Camera:
I took some shots with the Camera, as well as with the Cameras of an iPhone SE and an Olympus E500 see here:

Telephony:
Works, call quality is quite good. You can dial from the cover display and pickup calls. Nevertheless, the laggy display is unusable for dialling numbers, or selecting a contact from your address-book, especially if you have ~200 contacts in it. The order of the contacts is by first name, even if you change the order of the contacts in the Contacts-App.
