subscription models monthly payments

if its anything like the new Sonar price plan, then you have a choice - buy outright and pay for future updates whether u like or not, as u have paid already or go down the subscription route, get tied in for a year and pay more for the privilege. the following year u get a discount?

what if the product released does not work as advertised and full of bugs?

opens up a can of worms. no to paying for my fix monthly
