If I were invested in the whole Xbox ecosystem I would resent having to shell out more for a device that basically brings nothing to the table as a gamer.
Looking across at my PS4 'rivals' they basically get a more powerful console for a lot less money. To add insult to injury Xbox fanbois try and point out the flaws in the PS4 ecosystem, flaws which the XBox has too.. "Look, you have to pay for multiplayer now!", which although is a new added expense, was ALWAYS an expense for the XBox.
Microsoft have already tweaked the XBox OS (Whatever its called) to reduce the CPU and memory usage of this device, but in doing so they admit that their console is the weaker of the two spec wise. All the way resisting the overwhelming public demand that they need to drop the requirement for the device and instead pushing their "living room agenda". In this day and age people are price conscious, Microsoft forgets this.
Sure there are exclusives that tempt people to drop cash on an XBox, but the financial difference is so large, this "exclusive" system doesn't have the pull it once had. Microsoft needs to drop the mandatory add on requirement before its too late.
