Stupendous, that's a nice desk, i like it a lot, it's very similar to mine except i've got the straight part on the left side instead of the right.
Personal preference (figure out what suits YOUR needs), but i prefer a large, sweeping radius in the corner (like in Stupendous' desk), as opposed to a squared off/small radius corner. I just find it to be a lot more comfortable and practical. I love having the computer in the corner area, gives you a lot more depth and surface area to work with.
