I'm still hoping W10M will be there in future for my Ativ S, but I bought a Lumia 640 dual sim so I can experiment now with W10M and still have the Ativ S as a backup. Lumia 640 is nice, but Ativ S display and case are better.
How is this working out for you? Getting tired of the Ativ S at the moment. No updates, no support from Samsung.. I haven't got any hope left we're ever going to be seeing Windows 10 on it. Maybe unofficial, but certainly not official.
Getting a cheap quad core to replace the Ativ's Dual Core seems like a decent idea. Plus, the 640 over here is the only reasonable priced entry level phone with roughly the same specs. Although in my opinion, 8 gigs of memory is abysmal, esp. considering MS took away the only means to move HERE maps to SD card. I feel like every Lumia released in the past say 2 years has been intentionally crippled by just omitting a specific piece of hardware to differentiate it somehow from higher end models. Which is weird, cause there currently arent any real "high" end models in the Lumia lineup, hardware-spec-wise. Sure, every single one runs 8.1 a descent speeds, but it's with the release of 10, every model currently running WP8.1 will most certainly going to be sub-par, judging by the specs of the newly announced phones. And even the low to mid end Lumia's run 8.1 fast enough for daily use, so whats the point of even getting a more expensive model?
I'm not even sure i'm entirely fed up with the Ativ S only. Sure, mine's been having a lot of quirky behavior lately so the hardware might just be dying on me, slowly. Not being able to receive calls at times and having them go straight to voicemail (reboot fixes that but it is annoying AF), battery needing replacement (nothing out of the ordinary after 2 years of use i guess), GPS and Here nav stopping mid navigation.. But.. Slow progress on the WP OS in general, every major update (if we were even getting them as "2nd rate WP users - aka Samsung owners) adding one or 2 new features that are actually usable and a lot of new features that are implemented so poorly they are infact, utterly unusable (VPN anybody?) is something thats really starting to annoy me. Maybe even more then the Ativ itself and the lack of support on it.
Microsoft seems to be repeating their "Soon!" mantra over and over since they have been doing since they released the first version of Windows Phone.. And the progress on the OS development front, and app development front are both minimal.. I mean, the completely ditched the hubs idea which everybody seemed to like, even the Facebook app seemed to have been destroyed completely with the last couple of updates. Then they announce newer phones which are going to cost a boatload of money. With "Continue-em" as a USP. Nice. If you want to use that. Which i'm guessing the majority won't, actually. Then u got Android apps. Well.. Might just buy an Android phone then.. It's like they don't get it anymore at Redmond, or just don't seem to care at all. <Sigh> Too bad actually.
