I have the iCurve and both love it and hate it. I love the space-saving feature that you mention, which is why I got it. My PB shares the desk with my desktop PC so things were getting crowded. Right now I have a Belkin USB hub under it, which fits nicely. I use an external monitor, keyboard and mouse with it, but I often type directly on it as well, and for those times I find it too high. It also bounces a little when you lean on it, which is annoying. It's a bit of a toss-up, but if you already recognize the problems with height, angle and size, then maybe the iCurve isn't for you.
