Hardware firewall(NEWBIE)

[li ming1]

Some NEWBIE questions:     Are there anyone using hardware firewall?     Would you please tell me why you use(or don't use) hardware firewall in detail?     Since hardware FW can perform several thousands of rule matching operations in parallel, does             this means hardware FW always has more throughout? Is Hardware FW more easy to use?     What's the current market situatuion?     Is Hardware FW  the trend of the FW? Thanks a lot!
