Great review... Almost the same as I feel about the M8, but not quite...
Build Quality - The build is amazing. I loved my various Nokia handsets, but aside from the 900 and the 920, most of them felt a bit light in the design department. The 925 was gorgeous, but they omitted Qi and a few other features that would have made it a killer. Overall, Nokia doesn't make a piece of hardware that touches the M8 in build quality right now.
Software - This one is definitely going Nokia's way. Between losing Nokia Camera (DuoCam is ok, but the adjustment rings just flat out destroy two stage buttons for adjusments) and Mix Radio, it hurt a ton. Also the Nokia Video Uploader and Play To are absent and just don't have a good Win Phone replacement. HTC did work in BlinkFeed which I love and Video Highlights which is like a lite version of their Zoe software, but it's still not enough to keep up with the Nokia Collection. Maybe someday MS will release the entire MS Mobile catalog to everyone, but until then, Nokia has the edge in software.
Camera - Toss up, depending on what you are shooting. HTC's exposure system gives a more dynamic exposure, but Nokia's is larger. Nokia allows you to use a bit of digital zoom, while HTC does not - you can do it, but the results are pretty darn horrible. That said, in a blind test, about 90% of the people I asked liked my HTC images better than my 925's... So, if you aren't printing 8x10's, chances are the HTC will work dandy. It is also worth noting that the HTC does not have a physical camera button - which makes it a requirement to have the camera on your home screen. There is no button to unlock the camera without a password either.
Front Camera - I put this in to a separate category because this is the best front facing camera I have ever used. It gets my entire family in the shot at arms length and is crystal clear. Did I mention that it is a 5MP shooter? Yep, that's 'better' than the back camera, though the dynamic range isn't quite as good. Huge bonus for vacation photos if you ask me!
Battery Life - I used to make it 8-10 hours on my 925 with normal use. I don't even look at the gauge on the M8 any more. I usually have 40-50% left at the end of the day if I don't game on it. If I game on it, I can subtract about 15% per hour for that - and yes, it gets HOT! Now on the subject of Qi charging... they make adapters - no they don't work. Is it hard to give up... YES! I have DT-900 and DT-910's all over and I totally miss setting my phone down to trickle charge. That said, I only have to plug it in overnight, so I don't miss it that much. In fact, I think I benefit more by having my phone on me all the time than forgetting it at my desk when I would take it out to charge it. So, for me Qi is a mixed bag of I love it, but the M8 doesn't need it - so there it is...
Dot View Case - Cortana users take note: YOU NEED THIS CASE! All you do to access Cortana is swipe downward. You can then give it voice commands. It's awesome. Dot View is also great for answering the phone as it shows who is calling and all you need to do is pick it up and talk to answer. No swiping or opening necessary. Now, that said, the case does tend to get in the way while shooting photos, so be careful!
Ships Unlocked - Yes, you can use it on the AT&T and T-Mobile networks in the US. That said, it's not always 100% great on said networks. It seems to work ok on the Band 4 1700(d/e) bands on AT&T LTE, but T-Mobile is hit and miss. You will see HSPA+14.4 speeds on AT&T's 1900 band and in areas where T-Mo has refarmed the 1900 bands as well. Overall, a huge plus even without the LTE radios everywhere.
What's awesome: The build, the screen, BlinkFeed, BoomSound, Camera (speed and dynamic range), Front camera resolution and quality, HTC Advantage (free screen replacement), expandable memory!
What's not: No Qi or good wireless charging options, No access to Nokia software, Earphone jack on bottom (this doesn't make sense to me, but whatever), the 'downsized' versions of Android Apps.
Overall, the M8 is the phone I have been waiting for since the Titan was killed off. It is the perfect phone for me in size, weight, feel and design. My biggest issue is that I have to have a case on that gorgeous finish. I really like carrying this thing without a case, but I just can't do it much due to the fact I am afraid of dropping the thing. All in all, until Nokia releases a newer phone than the Icon, the M8 is a no-brainer in my book for those on Verizon and makes a strong case anyone that is willing to give up MMS features to use it on any other carrier.
