Nokia N95 vs Samsung i8510 - which one is better?

Nokia N95 was, and actually is, the most advanced smartphone in the S60 lineup. After a while Nokia released updated version, N95-8 which had 8 GB of internal storage and a larger display. However it is a mistake to think that N95 will be unrivaled. Samsung Company recently announced its answer to Nokia N95 - Samsung i8510. This smartphone on S60 platform has amazing specifications, and has all chances to become a real "N95 killer". Let's look closer on both smartphones (N95-8GB version and i8510), compare them, and decide, which one will be the winner of this comparison.

Design and controls
Both phones look very similar, both are made in form-factor of sliders. However, while N95 can slide in two positions, revealing multimedia buttons or number keys, i8510 is limited to usual one way of sliding. It is hard to tell, whether this is an advantage of N95, but it definitely is an original way to control your music or other media functions on the phone. Aside from two soft keys and dial / reject buttons under them, there are two unlabeled areas that look like buttons. Even considering them as unknown buttons, N95 has two times more buttons on its front, 8 buttons opposed to 4 in Nokia i8510. Both phones have 5-directional navigational button.
