Ok, so basically the retail Crucial M4 drive will be released in late April, but there are some Micron C400 drives being sold right now by some lesser-known retailers... Will the Micron C400 drives be available at major online retailers long before the retail Crucial M4 drives? Or the fact that Micron C400 drives are available is unusual and we shouldn't expect to see many of those popping up in sites like Newegg or Amazon until late April?
