Went to a Best Buy yesterday and they had both the Gunmetal and Silver/Gold versions of the M9. Played around with each for a bit and was generally impressed with the build quality. I currently own an M8, and while there are some minor differences, it was pretty much the same phone to me. Though I will say it was easier to hold since it wasn't as slick as the M8 and the side power button is a welcomed change (even though I've gotten used to double tapping the screen to turn on my phone).
Sense 7 looks just like Sense 6, albeit more customizable options. I do like the option to add a 4th navigation button, and would definitely add the Notification menu button since it's always a stretch for me to reach the top of my phone and pull down with one hand. There's also the option to add a button to hide the navigation buttons, which gives you more more screen real estate.
I did play a music video on YouTube and put the volume to max. Did the same thing with my M8, and in my opinion the M8 was definitely louder and had a richer, fuller sound. I mostly use headphone so it's not a big deal, but there have been times when I've watched videos in the car with friends, and the loudness/rich sound (and not even on the max volume) on my M8 always impresses, and everyone can hear with ease. So a little concerned there with the M9, especially since they "upgraded" to Dolby sound.
I took a few pics, but it was a little hard to judge the quality since the phone was tethered to the counter, so couldn't really take a variety of pics, so it was hard to judge. Based on reviews I've read, though, I'm a little concerned with low light situations.
With all that said, I've been an HTC owner since the Evo 4G on Sprint. Following a year of ownership of that phone, I got an early upgrade to the Evo 3D. Kept that phone for 2 years and then went to the One M7. Paid full price last year for the M8 since I wasn't on an upgrade year, the primary reason being that the M7 wasn't a triband LTE phone on Sprint, and the M8 was. Been very impressed with the M8 thus far. I've been averaging about 18-20 hours of battery life, and for me the camera has done great, especially in low light situations.
I was anticipating upgrading to the M9, but after the reveal and the reviews, I'm concerned with two things: battery life and camera (especially in low light situations). Also, knowing that my M8 will get Sense 7, it's getting harder and harder to justify; and I'm a tech lover and always love the newest and greatest. I'll definitely be reading how real users like the phone and may choose to purchase at a later time, but for now, I'll be on the sidelines and also wait to see LG's G4.
I will say that if you are on Sprint and have an M7 or own a single band LTE phone, the M9 is a great upgrade for the triband LTE experience (unless of course you are also concerned about the camera in low light situations, then join me on the sidelines or consider the M8, which will likely drop in price).
I agree. If you already have an M8, then the M9 is a waste of money. No increase in battery life. Won't notice a difference in speed. The camera on the M8 is better than the M9. But if you want a george foreman grill, buy the M9. Cook your eggs in a few seconds...lol
