screaminglemon did an excellent job of summing up my thoughts too. Lots of people have upgraded their 900 to the 950. I also like the speediness of Wi-fi compared to 3G, wikipedia integration and the improved multi-column view mode for PDF's.
However, if you like your 900 and you don't really need
any of the improved features, then maybe it would be better to wait a few months until the price drops more if you don't want to part with your money now. Your profile doesn't say where you are located. In the US, Sony has a trade-in program going through the end of the year. You can get a $75 discount if you swap your 900 for the 950.
