Ya the new version i guess is coming out in september, but i read that whoever has bought the UDM and register it, they will send out the retro fit for free once available. This is what I read. But reading the posts between the PC and the UDM, I mean ya the UDM is a bit more expensive, but the advantages might just be worth it. that is just my .02. I have never bought either before so i reallt have no idea.
