Well, obviously yes I could and so could my clients. But Free is the best kind of price, especially for startups. I have no problem paying for good software and services. I also have no problem seeking out the next option that compares in value. At this point Google Apps is a paid email option that must compete with all the other countless premium email options.
If a dollar a week is too much for what you get from this service then maybe you're doing something wrong, especially for startups where you're not going to have hundreds of employees.
