I’d love to have a half-decent keyboard (permanently attached but slide-out), with similar quality to those cheap bluetooth slide-out keyboard attachable cases you used to be able to get for early Samsungs phones (like the S3). I realise the small manufacturing volume would make it much more expensive. It would need to be permanently attached with rugged screws or similar.
But if Jolla has to choose between spending money improving Sailfish OS & spending loads on a h/w keyboard, I’d rather they improved Sailfish OS with things like:
Good VoLTE support on the new phone. Hopefully WiFi Calling as well!
Add support for FIDO2 USB or NFC keys (like from Yubico) to the web browser & Android AppSupport.
One point about the bus speed. 16bit 44kHz audio is 176.4 kbps. So, I can’t tick 100 but don’t need 1mpbs, either. Just saying, a dac could be in the middle somewhere. Most i2s dacs run at standard (i2c) 400kHz upper bound and have enough buffers to deal most situations gracefully. For comparison with very primitive embedded systems, a pi pico (at < 200mHz) can easily run a 16bit dac and an oled at the same time on the same bus. For the sake of audio quality (just in case) I usually run a second bus, but it can be done on one.
TOH is back! Loved the blue TOH from the original Jolla phone. The most important TOH-features for me are: 3,5 mm headphone jack and Qi2 wireless charging. Placing my pre-order after this comment.
Audiophile toh: smooth wood stucture back cover with integrated high end audio dac, analog class D amp, audio jack in/out, stereo speakers horizontal, stand, battery
I think a lora case would be interesting. Meshtastic is starting to gain traction and it would be interesting to see networks expand with active devices.
Not related to ToH but I would really like to see the device support video over usb-c to enable a convergent use of the device using keyboard, mouse and external monitor.
Sci-Fi Corner:
The GA or Para Pilots oH with ADS-B, FLARM, VHF Radio and barometric Altimeter/Variometer
The medical oH with medical parameter monitoring (ECG, Saturation) and Ultrasound (Iphone accesories for that have been in existence for years)
The Amateur radio enthusiasts oH with VHF and UHF radio
The avalanche beacon other half (granted all the specialised producers recommend to keep it 50cm away from phones, but for the SciFi there’s gotta be a way to avoid this.)
And for the blackout, the manual dynamo oH
Quite a lot of interesting suggestions before that, a multimeter would be nice, while I also favour any way to level the camera bump.
However, on the J1 I never really appreciated that possibility. never found a really convincing application, and over the years got occasionally annoyed by the set up ambience resetting itself after minor bumps.
