Running Update 5. Battery life good, getting a couple of days. Browser is just about usable, navigating sites and tabs is a pain. Loving the music player, simple to use, sound is excellent and navigating my collection is beautifully intuitive. I've lucked into a great mobile / headphone combo with a set of AKG450s. Anyone who has listened to playback has been very very impressed. Best thing is that thereis more to come, my tunes are in mp3 format from google music, starting to convert my CDs and Vinyl collection using Flac this weekend.
Some of the native apps are fantastic, Mitäkuulu, Tweetian, Friends, Sailbox spring to mind immediately as being Tier 1 level, upnpplayer picked up my LG tv and media collection on my Win 8.1 box without any issue.
I have all the available other halves, Snow white, First one, Black and Aloe with Poppy Red on the way, have had no issues with them being recognised or problems with fit. Does mean that I expect to have a full Ambience selection screen in about 3 or 4 months.
Mapping is accurate and reasonably fast, disappointed that I do we do not yet have live directions. I would pay an extra license fee for this functionality.
With regards Android apps, I am trying to keep away from them, only 2 I have so far are Viber and Skype and both are functional.
So to sum up, i'm impressed with the development progress, the UI has won me over completely and i'm looking forward to more native apps and development of Sailfish.
