Having the ability to upgrade a switch is a good idea for power users. However giving that option to alot of people has the potential for bricking and destroying the switches. The heavy users on here (ie:Teken, LeeG,etc.) would have no problems updating a switch. However there are many out there who can't even plug the PLM into the proper port. Not only that, you also have to take into account firmware changes can also involve hardware changes. In doing that and having someone update the switch, you could cause problems.
