It doesn't need to be in the same league. Getting a "real" multipurpose tablet for the price of an e-ink reader will be compelling enough for many consumers, assuming performance is not abysmal (meaning not a heir to the Maylong M-150: http://arstechnica.com/gadgets/reviews/2010/11/worst-gadget-... ).

If actual battery life 5+ hours (when watching videos) and it is just fast enough for e-reading, light browsing and most small games, I don't see why people wouldn't buy them unless build quality is really low. Then again, dubious build quality doesn't stop people from buying crappy TVs or bluray players.
