Ha, you don't know nothing! I assume you've heard about "usability". My other half, a technical writer by profession, attended some conference back in 2006 or 2007 and the buzzword at that conference was... "discoverability"! Just invented by Microsoft. I kid you not!

Nokia Lumia 928 lags behind iPhone 5 screen latency as well...

You know, I had a Nokia Lumia 900 that my wife took over. Then she upgraded to the Nokia Lumia 520 - a dual core lower-level phone that actually works quite well. For her uses, it's great. She needs to read some e-mails, make a few calls and love how simple it is.

I couldn't convince her to get an Android phone. She tried Apple and found it too "lacking" in what she wanted but could appreciate the workflow. She tried BlackBerry 10 (my Z10) and found an user glitch that isn't fixed as of 10.2 - you have to tap into the screen in order to activate the back/cancel button when you drill down/search via the Hub.

I find WP8 restricting. She loves it. I find Apple iOS7 actually not bad - it's got a lot of Android Jelly Bean features that I like, such as the notification center and the control center quite a bit.

Me neither, because my WinCE Lumia 800 isn't upgradeable.

This "study" really is ridiculous & insufficient. Nicely presented but without any usable content. But well, can be used to bother some Windows people...why not.

Z10 has a lot of usability glitches, like not dismissing missed call notifications from the hub (you have to open the phone app), firing notifications from the running app and flashing the led until you go to the hub ("skype has signed in". I KNOW! Skype is the active application!), inconsistent behavior in slideout menus, not dismissing sms notifications unless you click back to go back to hub, stupid two-step notifications etc.

For the specific glitch though you can just swipe right and it goes back (the mere existence of the back button makes this gesture undiscoverable (I know, I know) but it's there.

Good luck finding them. :P

I wouldn't say synonymous to - just, correlative with.

You can have the basic use-cases made very intuitive, and leave the other stuff harder to figure out. Unfortunately, in a 'study' like this, the 'other stuff' would end up being counted against the OS' usability factor.

Now I think we all know that the methodology of this 'study' could probably have books written just criticizing the flaws, but here's something I found really indicative of the fact that they are not fit to evaluate user experience from the perspective of new users:

No-where in their "UXF" ratings details, does one find mention of how on Android, first-time users might think that deleting an app icon from the home screens means you deleted it from the phone. I've witnessed first-hand the less computer savvy of users say/think just that (much like folks on desktops sometimes think that deleting the desktop shortcut deletes the program itself).

NokiaPhone is the best OS I ever have used
