According to my research, this is what i conclude. But im not sure.
Companys like ibm and google provides services of Virtual Machine on cloud, allowing me to customize the vm when i want to. And charge me for my hour usage according to the vm hardware specifications, wich i can also customize. At first the fee seems to make these cloud vm more expansive in the long run, but since i can customize the vm hardware constantly, and pay only for its current hardware usage, then i could change the vm according to my current needs at each moment, and pay 50% of time for a very bad hardware, and 50% of time for a very good hardware, or whatever my needs are. Lets say i use 60% of my desktop time to work, 20% to watch movies and 20% to play AAA Games. Each of these activitys uses a diferent cost of hardware. So is very well possible to have the same monthly cost a phisical pc would have, or even less, since the physical pc dont allow you to pay only for the time spent.
There is also the other economical advantages, such as the lack of assistence and ocasional acidents, as well the cheap high speed internet conection (once you pay for a 1-3 mb /s internet to receive the stream, the server internet do the rest).
Thee only problem i see is the privacy.
Am i wrong ?
