[Windows Phone 8 General] GoodDayToDie:
DataSense has nothing even remotely to do with backing up (and restoring) app data; where'd you get that idea? Vital feature that homebrew eventually made avaialble in WP7 but is missing in WP8.

"IS NOT meant" nothing! Somewhere under all that sandboxing and locked-down UI is a general-purpose OS running on top of highly capable hardware. It's "meant" to be whatever the owner fo the device *wants* it to be, including (in the case of many, many people if the popularity of WP7 homebrew apps is any sign) theming. Stop being an apologist for Microsoft; it's one thing to say "extensive theming wasn't implemented because other features were higher priority" but when you start trying to tell me that I'm not supposed to theme it, you seriously need to put down the Kool-Ade. Besides, the very claim is ludicrous to the point of disingenious; have you *seen* the WP8 ads? They all stress the customizability of the Start screen. To the point of suggesting you can "meet" a person simply through how they have their phone set up... those ads freaking scream "customize me!" Then you discover there's only a handful of pre-set colors, two background styles, and the ability to mess with the tiles; nothing else.

No, it is quite absolutely *not* for "security" reasons. Security means the owner of the device controlling the device's behavior. If somebody else (like, for example, the manufacturer of the device) is controlling its behavior, that is not security; it's lockdown. The sideloading restriction can only be called security if it's not your device but actually belongs to Microsft. Screw that. Besides, that argument makes no sense anyhow; if I can pay my $99 and sideload with a PC, why can't I sideload without one (or without paying)? The marketplace has DRM to mitigate piracy and that's a darn weak excuse to cripple a device anyhow.

When I can load my Puzzle Quest 2 savegames and other game progress and high scores, copy my PGP keychain, sideload my Kindle ebooks into the Kindle app (yes, this is possible on WP7), extract or replace the built-in audio files, and delete the junk which accumulates in the OS and uses up storage space (without hard resetting the device), then I will stop considering the level of filesystem access a problem. Until then, "running flawless" is quite worthy of scorn indeed.

Wow, I seriously question your reading comprehension. I never mentioned Android in this point, or anywhere else (except to point out that it has a lot of homebrew). But, for your information, the default permissions / capabilities handling in Android is just as broken as in WP8. The difference is that with Android, it is possible (CyanogenMOD did this, for example) to install apps without actually granting them all the permissions they ask for. On WP7, this wasn't properly possible yet, but I was working on a system to do it that hooked the app install process and allowed people to uncheck app capabilities they didn't want to permit.

Um yes, I'd like to remove the non-functioning Samsung apps (until they are fixed) that are taking up space on my phone's storage and making the Settings list longer. I can always re-install them if needed. Every other carrier or OEM app is removable; why should these get special treatment just because they have a field in their app manifest that says "install me in the Settings hub"?

Multitasking - true multitasking, where multiple apps can run at once - is nigh-nonexistent on WP8. Aside from things like audio background agents and once-every-30-minutes-you-get-a-few-seconds-of-CPU-time scheduled tasks, there basically isn't any multitasking (of third-party apps) at all. Fast app switching is *not* multitasking; every app aside from the main one is suspended, unable to do amything until brought into the foreground.

Changing file associations obviusly isn't a deal-breaker, or I wouldn't be using the phone... but definitely a problem. Windows has offered the ability to control file associations since at least Win95, and I think it was possible in 3.1 as well...

Changing the default browser and email client and calendar and dialer aren't "theming" by any conventional definition, but the point made above about theming stands anyhow: it's a matter of personalization. It can also be a matter of functionality (for example, the built-in email client can't handle S/MIME encrypted email at all and has no PGP integration). Or a matter of usability (I use folders a lot; it's a pain needing to expand a menu to get to them)! Or something else... the important point is that it should be possible. Every OS comes with an email client, but every OS except iOS (and WP) allows you to change the default email client, too. This isn't even hard to implement (the relevant registry keys were present on WP7, at least; carrying over the API to control them wouldn't have been hard at all); it's once again a case of Microsoft intentionally restricting what you can do with your phone. If I wanted a mobile OS designed by a control freak, I'd buy an iPhone...

Nothing more really needs to be said here, except that with filesystem access (create a symlink or junction in the apps folder, for example) this would be possible...

Many BT profiles, such as HID devices (for mice and keyboards), are missing from WP8. So far as I know, apps can't use the Headset profile either; the pseudo-turn-by-turn navigation on WP7 would give its instructions via the car's BT if possible, but Nokia/Here Drive must use the phone's speakerphone speaker instead.

When I can change default browser and text editor, create my own themes, enable features that a ROM shipped disabled (have you seen the thread by the guy who can't get visual voicemail?), sideload high-privilege apps (without paying for the privilege), and remove root certificates of CAs that I don't trust (in WP7, these were stored in the registry), then I will stop considering the level of registry access to be a problem.

If they're from the store, they aren't really sideloaded, just downloaded on a different machine. I'm talking homebrew, stuff that the isn't yet, or never will be, or *can't* be (because it breaks some policy of Microsoft's, or requires high privileges to work) put in the store. Besides, many of the most popular WP8 models don't have an SD card slot at all.
