Absolutely loving 10572 so far - had a busy fortnight travelling with work - and my L735 is my daily driver so couldn't risk loosing use or the navigation I was reliant upon... so, had to wait until Friday to finally update. Very impressed - from the get-go it's been so much more of a smooth experience. It feels like we're gaining back some of the speed that was one of the key features of WP, but there is, of course, room for improvement. I've run all tech preview releases as a daily driver since day one of the programme (at times painful, but always do-able) and this release has put a smile back on my face after really starting to loose faith in the programme and it's direction.
Have scaling set to 175% and it looks awesome - 4 column layout finally gives me what I always wanted with live tiles - before, a wide tile was *just too much* real estate to waste on niceties like news, weather and photos - but suddenly the move from 3 to 4 columns allows you to pin wide tiles at will and really benefit from the additional information presented.
No serious bugs experienced so far...
- few apps with blurry tiles (as reported above);
- camera sometimes seems to take incredibly blurry shots (bad focus), BUT is MUCH faster, will test more - also don't know if this release has resolved the awful video recording when stabilisation is on; (?)
- twitter doesn't load on mine - I was going to check to see if this is display scaling related;
All the recent app updates (mail, calendar, etc.) are also making the experience much better - this really is starting to feel like it is approaching release... just hoping they pile the hours in to bring back the epic speed and reliability of WP8/8.1 (I remember once complaining about an app problem only to realise I had not turned my phone off or restarted it in over 4 months! The reboot fixed that particular app problem.)
More personalisation options would be nice, as would landscape options os-wide (...plus clearing out the chaff in feedback so that new suggestions and issues can be identified and worked on!!)
