Summary: I had previously owned a Defy, which I found great. Had hoped that by updating I would be able to speed up internet access. However, that doesn't appear to be the case - perhaps TMobile have reduced the 3G service?? Very happy with battery life - almost got a week out of one charge!
Summary: I've had this phone for a couple of months and am overall very happy with it. It's the first non-HTC phone I've had for about six years (I've had an XDAIII, Touch Cruise, Desire, Desire S and Radar) and although I did rather like the HTC One, the lack of an micro SD slot made that a no-go for me. I carry 40gb+ of music with me everywhere and thiat isn't going to change until data roaming is substantially cheaper.
Pros: Size, speed, build quality, battery life
Cons: Not compatible with some apps, screen and camera not high-end
Summary: The main reason for buying this smartphone has to be the long battery life - it lasts me 2 days between charges. The second reason is that whilst it is quite large, it still fits into your hand comfortably - unlike some of the large screen rivals. The third positive is the dedicated physical camera on/off button which I have found useful Negatives: the phone is not compatable with all the applications available so you may find you may have a favourite that does not run...
Summary: Like others I find the current trend toward larger and larger handsets baffling and this plus the claimed battery life and decent size screen is why I plumped for this phone. So far I am delighted - the battery always lasts a day easily, often showing 30 or 40 % left at the end of the day. The form of the phone is great. Fits the hand nicely and the weight feels right. Screen res excellent, fast opening of apps, browser etc.
Summary: I've just ditched my iPhone 4s for this and boy am I happy I did so! iOS was getting stale for me and worse, it was actually getting in the way of doing business. Even though the Razr i is still on ICS, the phone is blazing fast with very little lag. I can't wait for the JB upgrade sometime in Q1 (hopefully!). The SD card slot is great and already expanded the Razr i's capacity by a cool 32GB. Plus, Google's music matching service is heaven sent.
Summary: Had it for a few months and I still prefer using it every day over a SGS2, SGS3 & N4. Great ergonomics, build quality and battery life, nice screen, good value & in spite of what a few people have said, I think that the camera is very good, especially useful is the baked in HDR feature. It's every bit as fast and fluid as any dual or quad core Android i've used. The only down side is the lack of immediate pull down options for short-cuts to auto-rotate, bluetooth etc..
