i thought this was MacWorld '09...? but anyways, a 250GB iPod is dumb, a 64GB Touch is very realistic.
I would beg to differ considering I don't think it is cost effective to use one 64gb flash chip, even two 32gb flash chips is still would be a little pricey. Just look at how many devices are using a single 32gb chip. Only Sandisk is using one 32gb chip, Creative, and Apple are both using two 16gb chips, not sure what the Nokia N97 will be using, nor the Samsung P3. However, a 250gb ipod would be cost effective.
If you want a device that has 250gb or more of space, there is the Archos series 5 which goes up to 250gb of space, only downside is the fact that it is a 5in screen, but it does have wifi, optional GPS and 3G support. There is also the Archos series 7, which is pretty much the same, but it has a 7in screen and goes up to 320gb. That right now the only devices that has more than 160gb capacity.
