For me who travel professionally it is an ideal addition to my tablet (I dropped the computer) for 2 reasons. 1) I replaced a Samsung 5p I was falling steadily, it's too big to handle with one hand (airport queues ...). For one, with one hand what is perfect even if suddenly ... it is smaller ... 2) I put two SIM cards, one French and one foreign. Management of 2 SIM cards is really very practical! All you need is internet on each and use Skype with minutes purchased to avoid roaming costs (it works). Otherwise, the phone is fluid, I have not seen the famous problem of bluish colors (in fact there is a setting to choose her color preferences). Price / Excellent :-)
