It depends what you are looking for. The Xbox has a strong online community, if you are going to be part of that, get one. However, if you are a more casual player and maybe not tempted by the Wii then consider the Playstation. I am going to be buying a Xbox or Playstation after my exams and so far I worked out getting a Xbox, with a HDMI cable, wireless adapter, Gold membership and various other factors will actually costs more than the PS3 (which I get a couple of free games with). So price is not really an issue when you compare the systems, for what I want when a get a next-gen console, the Xbox 360 will cost me £40 more ($80).
Also the Playstation is arguably more future built and maybe the Xbox 360's hold on the market will suffer
