I bought the phone as a private mobile phone. As a business phone is a Samsung GTi9000. Because the Nokia 5800 also had a touch screen, I thought I can not do much wrong. Not even close! This is an insult so as to sell a touchscreen user interface! - Response times of a key command about 1-2 seconds! - Often the finger tipsters are not recognized correctly. With the delay really a headache. - I am Nokia phone owners for over 10 years and have to say, because Nokia has to make up a lot. The Samsung also put the X6 good in the pocket.
I ordered the 40-EUR expensive X6 from Nokia. This can be at least decent service and is no comparison to 5800!
