The plummet has astounded quite a few people. Having bought in at a little over 12 and cashed out in the 70s It doesn't bother me a bit. I think I'll be picking some up before the inevitable holiday season spike.
Apple's just kind of stale right now - No summer iPods products, no real major changes to product lines (drastic) and people waiting out the transition to buy. I think we could see this coming. Fall should be good.
It's going down, sure. But "crashing"? Hardly. I just checked Dell's shareprice, and they seem to be on an even steeper downwards-curve. So while Apple is falling, it's not like it's the only one.
