I've still to fly the ERJ 170 / 190 (had hoped to last week on DJ but got swapped into a 737) but the interesting feature of this aircraft is it's nose up characteristic whilst on the ground.
Most aircraft types I have been on have a level or nose down characteristic whist on the ground, why is the ERJs different? Am I imagining it? Does this have any aerodynamic advantage / disadvantage on take off / landing (Angle of Attack etc).

Just pulling your leg a bit. It really gives no discernable difference in flight characteristics. Just looks kind of frumpy. There's a slight nose up attitude on the ground, maybe a degree or two but I think it's more exaggerated looking from the outside than it really is. I think it's a combination of the mounting angle of the engine, the fa

Most tricycle geared aircraft sit nose up on the ground to some degree. It's harder to tell with bigger aircraft, but it's there. Take a look at the Concorde sometime.
The MD-80/90, CRJ-700/900, and 767-400 are one of the few aircraft that sit nose down, but this is to allow more room for when the aircraft rotates or flares, as they have long fuselages compared to their ground clearance.

You're definitely not imagining things. My guess is that the E170 has the highest nose-up ground attitude of all common commercial jetliners. I like the looks of the E170 aside from that attitude. It just looks funky that way.
