Windows 10 for Phones will be previewed on Lumias with 512 MB RAM, too12
A few screenshots from the technical preview of Windows 10 for Phones leaked out yesterday, and they confirm what Microsoft was saying all along during the presentation. Besides the Universal tiled interface, a new unified Notifications system was shown, too, which will keep it all synced across phones, tablets and laptops.
Now, all this goodness might even be scaled down to run on Windows phones with 512 MB of RAM, it seems. There are quite a few of those out there, but if Microsoft has indeed managed to stuff the basic Windows 10 for Phones functionality in half a gig, that would be quite the achievement. We'll see pretty soon as the technical preview is about to hit developers' Lumias pretty soon.
