I think it's important for Readyfx to create a phone that will appeal to the majority and focus on niche markets later. Most users will use Android, along with the host of Google Apps. That will be probably 90%+ of the users. Lineageos will probably be the biggest aftermarket ROM base followed by others like Sailfish, etc.
Do we have any updates on release date? I know it's Q1 2019, but i'm itching to buy this phone.

One thing I'm afraid of is screen size. I know Chen said with the 6 inch 18:9 screen, the device will be smaller than the Moto Z dimensions, But I feel like that still makes the device larger than my preference. The most comfortable phone I've ever used size wise is a Galaxy S7 (142.4 x 69.6 x 7.9 mm). I feel like any bigger would make the device tough to handle without some grip. Hopefully they make it with some grippy materials. I would prefer soft touch surfaces (like the original Nexus One or the T-Mobile G2). Both of those handsets were premium aluminum feeling with some soft touch accents to provide incredible levels of grip. It may be a while until skin manufacturers make applications for this device (assuming they ever do).

I'm obsessively checking on this phone every day, haven't been this excited about a device in a while. Hopefully they release soon

Based on my research and existing phones with a similar display size, I'm thinking this device will be roughly 150mm tall, 75mm wide, not sure about thickness, but maybe 10mm or less. I sincerely hope it's as compact as possible for handling purposes, possibly smaller than I estimated
