What is the difference between a hiptop 3 and hiptop 4?

For starters there is not a hiptop 4 after the hiptop 3 there is the hiptop slide. There isn't much difference except that one has a swivel screen and that the hiptop slide has a slideing screen. The hiptop slide has less keyboard space then the hiptop 3. The hiptop 3 comes in only one colour silver, where the hiptop slide comes in two blue and scarlet. hope i helped xx For starters there is not a hiptop 4 after the hiptop 3 there is the hiptop slide.
