Targeted phone for hikers, nature lovers and all those who want to make calls without complication and in all circumstances. The quality of this phone is to be energy efficient: no unnecessary expense and therefore it has an interesting autonomy. But it becomes downright awesome coupled with a Mobile Phone Batteries Samsung EEB-EI1CWEGSTD. There you can from a month to tour the Ecrins with your small (e) ami (e) without any contact with the magic of electricity while calling regularly. Other appendices quality: (1) it captures very well (a priori better than the 3-G and exclusive 4-G), (2) it will not make available to untimely pay day and (3) do not bombard pubs and spam Oh yes! Another great thing with this device is the Samsung KIES software (free download on their website). This software allows you to connect the laptop with a PC (or a Mac, I think) and via the PC to carry all your addresses, music, videos and files from other portable Samsung. Very convenient for fans of I-Pods who also want a laptop that makes sense in nature and not waste time duplicating stuff. Of course, if one decides to throw his old laptop broken to migrate to Samsung, everything can be typed and returned in an easy way via Kies and PC (or Mac). Last note: I have over 32GB of memory via a card and it's good for the future.
