Plain and simple--it's (mainly) in black and white. Although the RU950/TSU3000 can display grayscales I was never really happy with them in point how they look on the RC itself (they DO look better in ProntoEdit, imho) and especially I wasn't happy with the visibility in a semi-dark or dark room (the backlighting doesn't help much, imho). So there are lots of prettier system files, but I did go primarily for usability. The system file is very dry and functional, no gimmicks whatsoever. The file itself is small too (about 100kb), so it will load fast to your Pronto, which is an advantage when playing around with updated versions. The majority of the pages will give you the possibilty of a direct jump to the other devices, which is another advantage in daily use. Please note that the labels are in semi German/English language as I am a German citizen. I don't think editing this should be a problem. So, It may not look as good as other but it's very functional.
