Buy Facebook or Not?

After looking into Facebook, knowing that their IPO is soon coming out, it is very important that we evalutate if Facebook is a good. buy. I have come to the conclusion that facebook would be a good buy fro holding for 2-5 years, and I would buy into it after 2 months (When the stock decreases from its intial price). I feel that Facebook is a bubble and it is a matter of time before it goes "Pop". Facebook does not have any capital where it can get its value from. All of the ocmpanies worth is in ideas, so if they were to sell the company, there is not physical assets that would be transfered (besides some computers). So i think that the stock price will be way overpriced, but will go up for a few years on customer demand before it flops.
