It would still be wise to get the Ketron pen drive and get updated, I understand that the update takes 2 hours to complete so this looks like a full throttle bit of kit, I have not go mine yet in the UK. AJ software is all well and good but if anything goes wrong when you load AJAMSONIC on, who will you point the finger at and who will fix it for you. And how big is his software thats talking a year to produce, its going to take a week to load on, don't forget to get a UPS.
Just my thoughts
