This phone is small enough to use with one hand and thumb. I would not want anything smaller in the range such as the active or mini pro.
The white colour is very nice and bright. The walkman button on the top with the camera and volume buttons on the side are nice to press.
The sound with Xloud enabled is very loud.
Reported problems of random restarting are now solved with an update. I myself havent had this problem.
Comparing this phone to an Arc sees it have all of the main menu options with the addition of the stereo speakers on the rear and a very handy front facing camera. The only downside in comparison is the screen, having a lower resolution, however Ive found the screen to be good quality when browsing the web and watching youtube videos.
Browsing is fast, with the double tap feautre making the words of the page fit to your screen. The screen is very responsive to the touch and there is ample space; you have 5 home screens, one of which I have totally spare currently and seven apps screens. Again, I currently have 3 spare after deleting un-needed apps. On this point though, there are many apps bundled with the phone you cannot remove.
For me this phone has been very positive and surprising in its quality and ability for a relative low end phone.
To conclude, for £100 in the shops this is a total bargain.
