Even considering the added drain on the battery (which doesn’t seem to worry anyone who designs an online store for such a device, and should be doable with the 22/5 hours quoted for audio/video playback), the inability to sync or access your iTunes library over Wi-Fi is, well… dumb.
Let me see if I get this straight: Apple finally has something that is usable as a home tablet (albeit too small for things like e-books, etc.), and cripples it?
Albeit for a good reason – selling music and ringtones is sure to be more profitable for them than entering the home media fray in earnest…
That is Apple’s big skill – toying with news and media outlets to maximize their visibility while delivering products that they will render obsolete before sales start to drop.
