Penetration Testing: Hardware/software secureIDs - pros and cons.

[eladexposed () gmail com]

Hello,
What are the pros and cons for using hardware RSA SecureID/Other and software with the same characteristics? 

For example:
http://www.rsa.com/node.aspx?id=1313

Let's say there's a company that allow only customers using the hardware SecureID to connect its resources - 
What might be the main arguments the company has to prefer the hardware and not the software? 
> From the customer's point of view it's better to have software installed (management, holding of multiple tokens, user 
> usage etc)
 
Kind Regards,
Elad Shapira ("Zest")
