So I went to the MS store locally and got to use a 635. I loved it. My hesitation involves the apps missing from the store. The lady working there told me its a non issue because she goes to the webite site of whatever she needs and pins that to the screen, thus making her own app. Does that really working on anything? It almost seemed too easy. If I want my bank, PNC, can I just go to PNC.com and pin it? How about tinder? Does it work that easily for anything? I was skeptical so I held off until I could get help from you guys...Thanks
