Both phones have similar size and weight, with the Artemis being slightly wider and higher but thinner (108×58x16.8 mm, 130 g) than 
the N95 (99×53x21 mm, 120 g). Front sides of both devices are dominated by their QVGA (240×320 pixel) screens. The P3300 has one of the smallest screens among Windows Mobile devices (2.8") but it’s still noticeably larger than the screen of the N95 (2.6") which, in turn, is the biggest display ever used in a S60 smartphone (except for the internal screen of the E90 Communicator). Normally the difference isn’t too noticeable, but sometimes it becomes quite apparent, e.g. in case of in-car GPS navigation where the larger screen of the Artemis lets you see the map and navi info more clearly and from further distance.
Like in all Windows Mobile 5 devices, the screen of the P3300 is touch-sensitive and the UI is pen-driven. The screen of the N95 isn’t touch sensitive and the S60 3rd Edition UI is optimized for keypad control. As in some situations using stylus and touch screen might be cumbersome, the HTC P3300 has been equipped with additional softkeys and also with a trackball/trackwheel combination called "RollR". The N95, in turn, has a 5-way d-pad and two soft buttons.
