I'm saving up the money which should I get 360 or PS3?

PS3 will save you money in the medium and long run. A charger which you will buy is $40 for 360. Wifi $120, Live $70.
Also it's been outsold by the PS3 for the first 30 weeks on this year and the last 3 weeks of last year meaning it's catching up and will be caught up by mid-2009.
360's diminishing lead coupled with the fact that it runs on DVDs gives developers little incentive to support it past early 2010.
Do you really want to spend more(accessories taken into account) only to have it face obsolence 2 years earlier?  One doesn't have to look any further than the original XBox if you need a taste of MS habit of dumping off consoles after 4 years and screwing over middle and late adapters.  PS2 still survives 3 years after the Xbox.

Also almost all "exclusives" the 360 have that the PS3 doesn't can be played on PC. You might not be missing as much as you think.
The same cannot be said for PS3 exclusives. You won't find them on PC.
