Groundpounder brings up another good subject to consider - the fly. Flys are are great addition to a tent, both pyramid or wall. They provide a place to cook without being inside the tent (not recommended in bear country), a dry place to store gear, and a dry/shady spot to hang out during the day without having to be cooped up inside the tent. I spend more time under my fly than I do inside the tent on just about every trip.
For a pyramid there are two types of flys to consider. The one that is normally listed as an option with the tent ties directly to the tent above the door and is staked out with two poles on the outside corners. It does provide some shelter just outside the door and is quick to set up.
The type I prefer is a full size dining fly that is set using a ridge pole and side stakes. The tent needs to be ordered with a hole above the door to accomodate the ridge pole which then slides through the hole and ties in to the center support. This type of fly gives you a much larger protected area out front. The downside is more poles and longer set up time, but in my mind if I will be at the spot for more than a day or two is well worth the extra effort.
Here are pictures of both types.
This is my home away from home.
