The entire model of modern corporations is residual incomes. Residuals are predictable markers for a business to construct their models and future progress on. If they can play on X amount coming in every month or year, then they can plan X expansion, activities and operating costs. The transition to residual started in the 1990's but didn't reach a feverish pitch until around 2000 when every business was attempting to find a method to transition into residual (monthly or yearly) business models.
The consumer is the one that got hosed in the deal because now virtually everything has moved to a monthly or yearly fee based structure. Everything from your food, shopping, entertainment, cars, insurances, home, software, whatever, is subscription based. In some cases, your hardware - cable modem, router, DVR, whatever, is subscription based. When you add it up, it all becomes a tremendous expense over many years. My father always told me, if they can slap a meter on it they'll charge us for it. If they could meter air, they'd be charging us for it. Think about it, your water and your bowel movements are all metered and charged for.
If I can find ANY lifetime offering I usually go for it. I've been working more towards a subscription-free lifestyle, progressively more as years press forward because I think it's all generally a scam. Chromebooks require no security or additional software, so they are subscription free. Remember that!
