too expensive for only 300mh/s with asics coming out.
Yea might as well buy a half-descent GPU as at least you could use it for gaming or resell to gain some bucks back.
When ASIC's finally arrives i don't see why anyone would buy a USB miner except for maybe novelty purposes.
This is my thought as well, especially considering they'd have no use after. It's not like you can unplug them when they're obsolete and then use them for some other purpose.
