We had the original Rainshadow when our daughter hiked with us. Great tent, lots of room inside for three actual adult people. Good ventilation (translates to somewhat colder than a traditional tent.) Pitched very quickly and easily, though it does need a large-ish tentsite. I used to rig a small silnylon tarp over the door as an awning, so we could leave the door/beak thing retracted and get more ventilation and more storage space for gear. The only thing I didn't much like was the single door at the head end - made entry and exit somewhat challenging.
The new one has more head room and volume. Would make a nice 3-person tent.
