Was at BB today (hate hate hate that store, but that's another story). Looked at the 1GB SanDisk and nowhere did it indicate that it would accept any additional memory. If this SanDisk does take a memory card, would someone please confirm? Will even go pay BB's current sale price of 80.
[Of course, I was being "helped" by a useless guy who, when I asked about the Zen vs. the SanDisk said - well, it's good but it's just sold out. 2 minutes later, as we were comparing other options said - you should just get the Zen, and when I asked him to confirm that he had just said they were sold out, said - oh, yeah, right.]
The one that is on sale is the 240, it does not take extra memory. You want the 140 if you want to add extra memory. That is at Office Depot on Black Friday.
