Sun Microsystems is soon going to start offering servers with Ubuntu Server installed on them. With all that Sun Microsystems has to offer, is this move worth it all?

Anyone can set up a server in their own home if they wanted to, I mean it's not that hard, there are a million "how-to" guides on the internet. You can easily set up a LAMP setup within minutes. But what about in a large corporation with a huge server farm which have an "unlimited" budget?
