hopefully this hasn't been mentioned yet, but the so called "lower" prices is total BS.
as reported on newsweek and thinksecret... "The 40GB unit will ship for $399 and the 20GB model will sell for $299, a $100 reduction in price. Apple is no longer selling a 15GB model."
the $500 price version will be the 60gb unit later this year. the new ipods are the exact same prices. if i was you, i would simply wait for the 60gb unit to drop than to think i'm actually saving any cash by buying a new one this week!
now, a real drop in price would be the 60gb for $400, 40gb for $300, and 20gb for $200. iPod mini well... $150/$100 from $250. now THAT is a saving... if you take it even further... the joke is really on apple, because everyone used the 15gb ipod to compare the size to the ipod mini when it launched and now with the new "price drops" people should really think about the new additional 5gb for the same $300 price! the new minis definitely need to be at least 10gb before i ever dream about owning one.
besides the extended battery life (which is a HUGE plus, but I've got used to it) and the size adjustment w/ scroll whell (big deal), well i'm a substance fan myself and honestly don't see a good reason just yet to shell another half grand for a new ipod. i just may with th 60gb unit, but i'm not holding my breath. (besides, we'll all get the new features with the latest firmware upgrade, so... they aren't really tooting my horn all too much.)
just my 2 cents...
