Both are good devices but are also rivals. The N900 was released in November last year while the Samsung Wave was released in April, this year.

The N900 is really big with 110.9 x 59.8 x 18 mm, 113 cc dimensions while the Samsung comes with 118 x 56 x 10.9 mm. The N900 is most definitely the brick here. The Samsung Wave comes with something new called Super AMOLED capacitive touchscreen, 16M colors which normally is used in the Nokia’s but the rival comes with a regular TFT resistive touchscreen, 65K colors,. The Nokia N900 comes with Proximity sensor for auto turn-off, Accelerometer sensor for auto-rotate and a full QWERTY keyboard which the Wave lacks but in return comes with much more Accelerometer sensor for UI auto-rotate, Multi-touch input method, Proximity sensor for auto turn-off, Scratch-resistant surface, TouchWiz UI 3.0, Handwriting recognition and a Smart unlock. The Samsung Wave comes with 1.5 GB system storage but the N900 comes with 32GB internal memory beating the Wave by far.

Both camera’s are good with the Nokia N900 having the advantage of Carl Zeiss optics beats the Wave. The Nokia N900 comes with Maemo 5 which makes It very good for the Linux user as it is Debian-Linux based but the Wave comes with Bada OS which is not so bad after all.

The Samsung S8500 is beating the Nokia N900 with 600 h (2G) and 550 h (3G), the Nokia N900 has 278 h (2G) and 250 h (3G).
