um you can still buy the songs with zune and its the same pricing as apple. really there are no downsides to the zune other than the lack of apps that the ipod touch has.
here is a comparison: http://www.pcmag.com/image_popup/0,1871,iid=243285,00.asp
they are pretty equal (except the apps as i said) but I still give zune the edge because of itunes. itunes is possibly the worst piece of software ever written (unless you are on a mac, where it actually works properly). apple’s coders for PC are lazy and the pc version is a *edited*ty port full of bugs and memory leaks. zune gives you the versatility of using whatever software you want to transfer music to/from your device.
