You say you have had multiple ipod touches.. i think it would be safe to say you never got the iPod touch 4.. when i think of zune i subconsciously think "no facetime, no hd video rec, no microphone, etc." <-- ugh
I have had multiple ipod touches and have to say the zune hd is better. the screen display is way better and the overall layout is amazing. The sound quality is also alot better than the ipod touch. I recommend this to anybody who has an ipod.
