From my experience
Keypad - Yes , not easy if you are used to any other phones . If this is your first moile phone , then within some days you will be very familiar with it and no problems
Camera - Excellent , of course no flash , day time photos are great , at night not very good
GPRS , Email , BT etc - Very good , I tried almost everything with this . POP , browsing , connectin to lappy etc , no problems
Reboot - Yes , there is a problem , but I have seen this for many nokia phones ( hanging and rebooting - extensive use of GPRS may lead to hanging ) . This happens like once or twice in a month - for me , I didn't feel like a big problem
Shape - This is not the typical nokia shape , more like SE phone , so if you are familiar with other nokia phones , it may take sometime to get adjusted with
Sound - Yes , mono , basically 3230 is more into business class , might be the reason . Those who wanna make ur phone an mp3 player , yes this is not that good
Build quality - Excellent , no doubt in that
Display - Quite good and very nice for browsing , email checking etc ( do not expect the PC look ! )
And finally - Does 3230 sux ? For me - No , my requirement was a business phone and 3230 works pretty well for me .
