I have noticed the last couple of weeks or so that the staff twitter on the lower bottom right corner of my homepage does not update. In fact, there is nothing where there should be writing within their tweets. It shows their names etc., but after that they are blank.
Buyers remorse. It happens all the time. You not buying a new PC or console in a long time is alarming, but if you intend to game on a regular basis then you can rest assure that you got/will get your money's worth with the PS4. I'm sure you compared through the features of recent consoles and games for them and you came to your conclusion for a PS4.
You can't go wrong either way, but good lord, UPGRADE YOUR PC.
