If it is only those three changes I am not very interested of upgrading since I never use the auto-router.
That is unless the upgradeprice is really low (that way I am already prepared for v8 which might have more interesting upgrades).
And I agree on the computerlocking, it is a pain in the ass. I have a compiler that has that, changed my hdd to ssd bang had to call the company to change the license again.
Then I normally change (upgrade) my computers/laptops each 3years, where did I have that license key etc. etc..
