Definetly not.
I have a good PC and a PS3. I got a 360 in 2009 but I didn't really see the awesome-ness in Halo nor Gears and as time passed by I realised that there were very few exclusives per year that Microsoft puts out (obviously its their strategy and thats fine) but for me, who's a core gamer and appreciates first party exclusitivity, Microsofts Xbox 360 is not worth my time nor the online fee payment. This is obviously in my situation as I rather play multiplatforms on the PC (more cheaper!) and I am a sucker for Sony's first party and the PS3 exclusive games that push the hardware. And I'm a class A+ fanboy, just look at my signature.
Some friends of mine got a 360 at launch, luckily I've managed to show off some games and most sold their 360 while others never logon and lack XBL.
