I've had the 928 since early June and am rather happy with it. I am not one for apps, esp. since the credit/bundle with the VZW purchase ran up about a month ago, however the restrictions by MS on the phone's sw are the cause of most annoyances. I am exposed to phones a lot with work, and after the iOS 7 update on iphones, I'd say apple has drastically strayed from their optimization of UI on the minimalistic hardware that a respondent likened WP8 to iOS with: all the 4s's and some of the 5's I have worked with are horridly slow in the native settings menu... I mentioned how I despise Apple products, but I thought the performance was embarrassing on the devices!
The only lingering thing about my phone that bug me are the lack of microSD, an internal battery, horrible NFC implementation, and a lack of data/info/configuration on core components.... How difficult is it to let me know what my link speed on 802.11n is, and why is denying me this info making the phone better?
I do not see a need for quad or octa core chips on WP8 in the same screen-size as my 928, and I would rather see custom contexts for voice/volume/sound/brightness and more granularity to them than a larger screen or higher resolution... though, having a micro-HDMI out port would be nice, and one of the stacked batteries like the new LG has would be nice.
For the time being; I try to charge my phone between 85-100% battery level, charge with an ext charger powered by Li-ion or Nimh cells (undervoltage), and/or place the phone on a cooling device while charging: The lasting thing I want is the internal battery crapping out before I am eligible to upgrade. Really a shame all the carriers force you to purchase a data plan.... I regularly see "1.9 of 2gb remaining" in data sense, with only 3 days until it resets, but that is more hatred toward VZ than my Lumia.
