This is my first smartphone, so I have no other smartphone experience to compare it to. I have owned it only a week, but I feel compelled to review this already because my experience has been so great.
The Platform: What I love - Windows 8 platform. ease of changing around the tiles and changing the size of tiles on the home screen, being able to make a shopping note and pin it just above all my other tiles where it is easily seen when I look at my phone, being able to pin the contact info for important people right to the home screen, the store has all the apps I need. I am not a gamer, so that is not an issue. I really want it more for productivity and social networking, and it seems to have everything I need for that. By the way, I (and my kids) love the flashlight app! Very awesome!
Battery Life: For me, battery life is great, but I am not a super heavy data user. At least I don't think I am. I have spent a lot of time on the phone just getting things set up and learning how to use it. I think it has gone down to maybe about 85%, maybe a tad bit less, by the end of the day, and then I just plug it in at night.
Durability: After reading other reviews, I was worried about the screen breaking easily; however, before my phone case arrived, I dropped the phone onto the hardwood floor; it dropped on the face, and the screen did not break and the phone did not scratch! If the edges had not been rubberized it surely would have scratched around the edges. I do have a screen protector on it, so I didn't expect the screen to scratch, but I was hoping it would not shatter.
Design: The size and shape is great. I had a smaller slider phone before and I never felt like I was speaking into the speaker, but with this phone, I do. Speaking of the speaker, the sound on this phone is really great. It sounds like I'm talking to someone in the next room, and the speaker phone is nice and clear and not too tinny sounding. I LOVE the sound of music through headphones on this phone. Very nice. I think I will really enjoy listening to my industrial workout music, as well as classical music. The only thing I worry about is that the phone is thin on the edges, and the ability to grip is not so good; until I got my case, I was afraid I would drop it all the time. I ordered this phone case : Diztronic Matte Back Black Flexible TPU Case. I love it because it has a thick edge around the front opening that is just thick enough to protect the screen if it falls. It also provides a more secure grip. The only complaint I do have about this phone is that, without a case, the buttons are not so easy to find, and I found it difficult to know if I was pressing them hard enough. The case that I got for it solved this problem. It is much easier to find the power button, and it is much easier to press the other buttons (volume and camera). I do wish that I could just touch the screen to wake the phone up, instead of having to push the on button, but that is a really minor complaint.
Camera: I LOVE this camera, and it will definitely replace my pocket camera. I took some pictures without the lights on in my house at night to see how well it could perform. It is awesome! I couldn't even see my son (the subject) through the viewfinder because it was so dark, but after the flash came on and the camera took the shot, I had a perfect, bright picture of my son. The flash is really great, and the camera shoots pictures very quickly, with very little lag time in low light and none in full light. Totally opposite of my pocket camera (which is a great brand but is horrible compared with this phone). I love the front-facing camera, too, though I wish the quality on that camera was as great as the back camera (which is awesome, crisp, clear)
Checking Voicemail: I am used to having to call voicemail manually and give my password every time on my old phone. With this Windows phone, it stores my password and calls voicemail automatically for me. The first couple of times, I didn't even know what the phone was doing. It's great! I don't have to stop an put in my password every time I want to check voicemail.
Further information about myself as a user: Though have not had a smartphone in the past, I do have both an iPad and a Windows 8 laptop and can easily move around in both of those platforms. Furthermore, I owned and Android tablet for a short time, but I returned it because I did not find the platform as intuitive as Apple iPad or Windows.
I HIGHLY recommend this phone, especially if you like or plan to upgrade to the Windows 8 platform.
