I don't just harp on the lack of LTE, which is significant, but also the fact that LG builds garbage. If you think corners aren't being cut to make the phone that price, you're sadly mistaken.
I loved the Galaxy Nexus and was dead set on selling my Galaxy S3 for the next Nexus. As soon as I heard it was going to be LG I gave a resounding "NOPE!" ****, LG themselves have basically admitted they crippled the Nexus to sell more Optimus Gs. If I was a betting man, I'd put money on Google being VERY upset with LG right now. That being said, the Galaxy S3 is amazing, and the Note 2 is absolutely incredible. Flash AOSP android on there and you have a great device.
Now, as for WP8... I gave up Android cold turkey for the 920, and I initially loved it. There are some minor things that drive me absolutely bonkers though, and it's not just app selection. In fact, app selection is the least of my concerns, as I have 95% of what I used on my Android on my Lumia.
- Ringtones & notification tones: First, my alarm. While it was blaring on my previous phones. Not sure wtf is going on, but it's low. Second, I prefer having a different tone set up for different things, and obviously that can't happen on WP8. Not a deal breaker, but annoying.
- Nokia Drive: In my area, it's not that great. Odd routing choices are my biggest concern, but the nav doesn't feel "finished", which is odd considering how long it's been out. Not really a complaint as it's just not what I'm used to.
- The email app: I use GMail for all my mail. I have an older personal Gmail account, a more professional, recent Gmail account, along with a yahoo spam account and a Live.com account for WP8 that all comes into my "professional" Gmail account. That being said, I LOVED Gmail on Android (obviously), and I hate the mail app on WP8 for 2 main reasons: First, having to download pictures manually on EVERY email I receive, instead of having an option to remember my preference. Second, I'm kind of OCD about all my deleted mail being marked as read, and with WP8, I have to select about 20-30 each morning, mark them all as read, then select them all AGAIN, then hit delete. Why the **** can't the mail app just remember which were marked? Works just fine on Android, doesn't here. This is silly, but it's a major annoyance for me.
- Apps that I do use have horrible ports: Yelp is a disaster on WP8, and Untappd (Think 4Square for beer) doesn't exist so I have to use the web page. Rowi is nice but Plume is 100x better. NextGen RSS is actually amazing, and I have no complaints about it, as compared to GReader by Noinnion. Facebook obviously blows on both platforms, but it's MUCH worse on WP8.
- Google Voice blows: I use Google Voice for my voicemail, and post my GVoice # for texts when I sell things on Craigslist. The best I've found is Metrotalk, and it's not great by any means. I can't really complain since it's a Google based service, but it's something pushing me back to Android.
- The Dialer: No T9 dialing or even a predictive list based off the number you're entering? Using a 3rd party dialer app makes you confirm everything before you call? There's no reason for it. This is a MAJOR annoyance for me.
Now, the good: WP8 is a breath of fresh air design wise. It works, and it works well if you can come in with a clean slate. For a first smartphone, I will ALWAYS recommend WP, and for those who want simplicity this is definitely the OS for them. The home screen and live tiles are great, and the information is right where you need it. I just don't know if it's enough to keep me. I originally got this phone as an iPod replacement, to be a spare phone. I LOVED the music management on WP7, loved the Zune player and software, loved wireless sync. Of course, Microsoft had to ditch that feature, so... Yeah. Still making up my mind. I will say that if they EVER made an Android phone as well built as the 920, I'd buy it in a heartbeat.
