You also get free updates for life and all updates can be downloaded straight to your handheld unit from your PC/Mac. JB units will always require hardware upgrades which do cost more money (ie. JB4 stage 1 to stage 2 or JB3 to JB4).

I update my JB4 firmware with a laptop & USB cable - updates are downloadable, no charge.
