I still see more value in a slow but helpful app, than in a fast but nonexistent app, even as a user. Also, making it work first may help in prototyping, and I may even find out that the prototyped idea doesn't work, so I'll scrap it. Speed would again be wasted in this case. Or the customer may say he wants something changed. This is more critical to find out initially. Paraphrasing Stroustrup, if you're complaining that something is slow, it means it's so valuable to you that you're still using it anyway. (Ok, there are limits to that, but I think you get my point.) edit: Now that I think of it, I'd say that speed is a spectrum (i.e. non-discrete). One may be at various places on it; and one may have varying needs as to where it's acceptable to be.
