Windows phones were really solid, OS was very user friendly and stable. I personally didn’t feel the “app gap” that a lot of others complained about but, I use my phone for browsing, calls & text. If I recall correctly it was also ahead of the curve with PWAs, integrated them really well. And price/performance was good on some models like the Lumia 650.
I recall playing the tutorial. Never went online. Dial up sucked. Interesting tidbit, if you shoot your drill instructor at the range you’re dropped into a prison cell at Fort Leavenworth. All you can do from that point is listen to somebody whistling and drag a tin cup across your cell bars.
