Generally speaking, you’re probably not going to find any Fortune 500 companies that use shared hosting. If you’ve got that much money on-hand, you’re going to go with dedicated hardware - and probably a lot of it. That goes even if you don’t really need dedicated hardware, because big companies don’t like to take chances. For them, cost isn’t really much of an issue.

technology limitations with PHP and shared hosting.
The main issue here is that you are sharing the same server with a whole lot of other people, meaning that anything they do has a potential to affect your site’s performance/stability/security.
Also, on a shared server you don’t get quite as much flexibility as you would on your own hardware. Need to edit the php.ini file? If it’s your own hardware, go ahead. The only person you could possibly hurt is yourself. On shared servers, though, we can’t allow it as you could cause problems for others.
You also don’t have as much flexibility in shared hosting with regard to installing 3rd party software (ie. mod_perl, Zend Optimizer, etc) - even if such installations would be technically unsupported on dedicated, at least you have an option.
Of course, since I’m Mr. Official DreamHost Guy™ here, and this post is looking suspiciously like I’m trying to sell you on a dedicated server, I’ll leave the rest to the other forum denizens. :>
