you sound like me... urban riding is fun. Get a specialized P2. Its the best thing out there for the bucks. got mine for 650. i've taken it off of MANY jumps, some jumps up to 6' and have crashed a few times falling like over ten feet out of the air and the bike is fine (after i upgraded to DJIII cuz i broke my stock forks). as for Urban stuff... the bike rules. I've taken it off of staircases with a vertical drop around ten feet, rims aren't that whacked out either (i weight 185).
my bike weighs about 30 something pounds cuz i got a Bashguard and a DJIII fork seriously weighting it down, yet i can still bunnyhop cleaning up onto things 2.5 feet high, and with the bashguard about 3.5 feet.
for trail riding its not too bad if you are in shape... i can keep up with most people on XC bikes in very rough terrian (smooth stuff they will pass me by its not geared right).
the tires are massive, and have lots of grip. breaks work well if you adjust them right. The geometry and frame is what really makes this bike so great.... you can do lots with it. the one major part about the bike i hate is the forks it came with... they suck. Just ride them and then get a crash replacement for marzochiioooos (however you spell that), but if you are only doing some jumps and a smaller drops you probably won't even run into a problem (my friend has the same bike and does everythign i do and his are still working so maybe i had a bum pair). as for the kona bikes i looked at them too... they are good but i dont' think you get the same amount for your money.
oh... if you are doing urban stuff i'd stay away from a hardtail... you can't do manuels or bunnyhop real well on them ( i can't atleast), and if you want to do some trial tricks... its nearly impossible. you don't need a dual suspension bike to do drops that are less than around ten feet.
