OK, my summary:

Got my Jolla in december. My only smartphone, until that moment, was a Nokia N900.

As a phone, no problem. But I'm feeling both GSM/3G and Wi-Fi reception quality are slightly worse than N900's. Got no experimental proofs; it may be just psychological.

Silica UI and gestures are absolutely delightful. First sight love.

Stock browser is unusable for me, because of the "image-link" bug (question 23243 on togheter.jolla.com). Luckily, Webcat available. Impressed by the GPS app: about 100 times faster than N900's when loading and making "lock". A shame it doesn't offer offline maps. About media, the phone is powerful enough to play everything, but it's a step back in terms of formats supported. That XviD issue is a pain in the *ss.

Other apps are OK. I'm not a big fan of collecting thousands of them: as for now, only 32 installed. Not running "Androids" at all.

Love all those OS updates. But hate the fact that Sailfish isn't 100% free. Seems it's even less free than Maemo and... Android? Anyway, the phone is as "hackable" as the N900. But missing that Maemo "debianish" way of doing things. Sailfish seems to be in a permanent "beta" state, but that's something N900's users were used to. It's funny.

OS and apps are consuming a lot of RAM. Maemo was OK with just 256 MB and several apps running. It would be almost impossible to run Sailfish on a N900.

Seems battery is better than N900's, but doesn't matter to me. I'm always close to a charger and rarely has dropped under 50%.

Hate the on-screen keyboard, as I've always hated them. But Jolla's is highly customizable and prediction slightly relieves this pain.

Waiting for full copy&paste, 4G and usable and fast browser (Webcat suffers from some lag). XWayland and 100% free OS would be great. As for the hard, two "halves" would make it the perfect handset for me: an E-reader and a hardware keyboard.
