Yeah other than Look and new hardware features Like Monitor touch screen (Which Btw would require a Monitor that Handles that) Technically, they could Let Windows 7 Have that feature its just a matter of Software drivers and accepting the touch the same as a mouse click... Really So far they will just be chargeing Money For things that should be handled with the Sale of the operating systems we already own, Even if Windows 8 Has an Improved Software core better Firewall security and stuff again thats all things they can remedy with patches and re write Windows 7, the Only reason they wont or stop updating is because thats there force handed way of getting Money, That said its hard to dictate whats fair for us or not, If in the end microsoft feels they arnt getting enough money they have an Easy Solution to the problem that would Really tick us off,
They Could be like virus software protection companies who Relized that They need income every year and everyone who needed virus software protection Already owned it.. So after 10+ years.. they had to change the way their software works to be a Payment for Limited time instead of somthing you bought and could always get free updates for years and years and years..
Could you imagine Paying microsoft like 30$ a year for your operating system use of YOUR computer!?
if enough people Like me dont buy whatever Microsoft Sells Next.. It may be in the future down the road like 5 years from now.. but in the end all it will do is inspire Another Hacking Revolution of rightful justice.
