Finally, updated to Denim. Whole night's dload and installation went smooth. Woke up this morning to a "Welcome to Lumia Denim" notification

First thing I did was, charge the battery

And honestly, charging in Denim is super fast compared to Cyan. Usually will get btwn 30-40% per hour charge, but after I've done bathing n dressed up ~30mins, I checked the phone batt status and it showed 57% per hour (everything was on.. lte, wifi, gps, cortana, and essential bground apps). Excellent!
Then, the tile arrangement begins.

Loving the live folders.

And now the Battery Saver (small) tile shows the percentage whereas it didn't in cyan.
Also, FINALLY a data switch in the notification centre. No more going into settings just to turn on/off data anymore.
Anyway, wish it had the Lumia Camera 5 but alas due to hardware limitations. Bummer.
