Absolutely, 5.5 inch 16:9 display implies 122mm display length. Allowing 10mm to 15mm each side for the bezel implies between 142mm to 152mm device length unless they can achieve great feats with the top and bottom bezel size.

Yes it is true that size is less universally comfortable, therefore repositioning the device one-handed could result in dropping the phone. EDIT: Actually regardless of hand 'length' I completely see your concern is correct.

Just one more crazy request from me:

Chen, please include the possibility in the Indiegogo campaign to pay extra for a Sailfish logo on the back of the device instead of the Livermorium logo. The idea being when people see this sleek device, to 'promote' investigation into Sailfish OS. You could still use the Livermorium logo but much smaller on the device.

Ideally, the SailfishOS.org website should have an "approved devices" page, which would connect-up the public awareness strategy better, and given that Jolla seems to have shifted to become 'software vendor/integrator' then that "approved devices" page might be soon on the horizon.
