And I would lose the level 4 lisence on my router boards if upgraded to leve 5 or 6. So I decided not to. Why can't MT keeps those changes + upgrade discount option as well? E.g. Upgraded to the next level is cheaper than a new one but can only be used for the same Hard-disk ID as the previous lisence level. This way MT can be sure that the upgraded lisence is not used in a new hardware.
Just my 2 cents but I believe that MT will earn more sales if this is available.
