Windows phone for 5yrs and still???

Fired up my 925 when my wife left her Idol 4S at work Friday. She still really loves that phone and it's still working fast and fluid on WM 8.1 . The wifi calling and HD voice still sound awesome and that Olead screen is amazing for it's time. She almost didn't want to put it away after she got her Idol 4S back. :-)
 
I am still on Windows Phone since 2012. Started with WP7.5 (Lumia 710) then WP8 (Lumia 520) in 2013 then WP8.1 (Lumia 1520) in 2014 which I am still using until now. I upgraded to WM10 but recently I reverted my Lumia 1520 back to WP8.1 and replaced the battery and I am getting 4+ days on a full charge, so I am still happy with the system and have all the apps I need and can do everything I wanted from my phone. No plans to consider Android or iphone. I am waiting for the Surface Phone to see if it will be a worthy upgrade.
