wow, that's already 5y ! in my case it's about 4½y, and still use it every day with the original Android OS, v9 i believe. because of that i can't install one or two other apps i would need, notably Leica's FOTOS app. ithe Pro1 has its quirks, just like the N900 had it. it's a shame that no big player phone maker produces such a thing - while for a tiny little company like Fxtec it's quasi impossible to come out with a perfect mature product. anyway, i love my Pro1 as it is, and use it every day...
