[General Questions and Answers] 3clectic:
Definitely subjective

Got a WP8 / Lumia 920 for XMAS. IMHO, this is what I feel after the first 7 days with this device.

Positives - native integration (SMS backup, FB (which is functional but limited), Twitter, LinkedIn, SkyDrive, Office & OneNote), smooth interface, live tiles (but gets gimicky after a couple of days, however, for the People tile, can be a good reminder to get in touch with people when you see their FB contact photos), stable, just works out of the box without too much configuration, heavy (good and bad), solid construction, learning curve isn't that hard, integrates well with PC's (as in can see phone storage, etc...), IE is actually quite good (which is good as other browsers haven't been ported yet), screen & font on default is very easy on the eyes, camera (hands down best one yet, compared to SGS2, SGS3, SGN1, SGN2 & BB)

Negatives - single volume control (i.e. no different volumes for phone, system notifications, alarms), no file explorer, no native network UPnP players (expectation appears to be buying an XBOX Live subscription), lack of apps ((I know, it's been said a million times but coming from Android, where I have found my "core" apps, it's really frustrating have to pin websites to the start screen, as the OS stays around should be rectified), Whatsapp doesn't appear to work unless it's "open" (which I am still trying to figure out and know it's more an app problem than an OS problem but had no problems on the Android platform), no "real" task manager, SMS delivery report is treated as an incoming SMS (other phones have a tick that appears next to the sent message, when the delivery report is received), to accept FB friend requests you need to install the app, battery life (lasts about a 6 hours if I use it normally, which was roughly the same as the SGS2 with JellyBam), unable to edit a typo'ed word (if you type it in and it doesn't auto-correct, you need to delete and start again), FB messages unable to upload statuses with the people that are with you (unless you use the FB app and not the integrated system, which for me is annoying to have two different mechanisms for the same thing but with different features), have had 1 random restart, everything is contextual (good - you can find stuff in a single app & makes some activities easier, bad - sometimes, I just want to see what is in a folder, not what music is on the device or do stuff that the developers haven't figured out the people do yet, similar to copy and pasting phone numbers in BB with spaces, it doesn't recognize them as phone numbers in the call screen), email client doesn't have a "send as xx by default" so you need to choose the email address you are going to send from when you start the message (maybe there is a switch for it but I haven't found it), unable to add custom system notifications (but can add ringtones??) for messages and emails

Core apps waiting on porting - Pulse.Me, Springpad, Wunderlist, XDA

Core apps (or alternative) - TunedIn (in place of DI.FM), OneNote (poor replacement for Springpad/Wunderlist)

My feelings - This really feels like a v1 OS and there are some things missing that I think were there in previous editions. I had an O2 xphone II about 7 years ago, which I really liked. Rock solid, could get a bunch of apps and was small light. Since then have had Tytan 2, Sony Ericsson, POS dumb phone, BB Bold 2, SGS2, SGN1 and then this one. The only tech that I don't really like is Apple (although, I think their hardware is pretty good, have never really liked the OS, but meh, that's a personal thing). I am considering selling the Lumia and going back to Android, however, want to give it a month or so, to really make sure that it doesn't fit me. I like to be able to stream music/tv shows/movies to the phone when doing household chores, which I miss with the 920 (although, have found a UPnP player but that means I need to go through and update all my files and some of the files can't be played by the 920 although it's listed).

Some parts of the 920 are awesome, some parts are really frustrating that it's missing.
