In fact, I think the Arduino team is to be commended. Being able to have Arduino-mega in the hands of REAL USERS on the date it was officially announced is a real accomplishment. The distributor pipeline is primed with product and ordinary users can order one immediately (and apparently receive it slightly faster than the distributors thought!) That's practically unheard of, and it's wonderful!
I can vouch for Arduino excellent work in getting the mega out to the Arduino community.
Like many I saw the "leaked" pictures of the Mega Arduino, thought "hey I want one of those", checked this site to find no announcements so I contacted my local UK supplier coolcomponents.co.uk who said there would be an announcement made on Thursday 26th March and to get back with in touch with them then. So I waited until Thursday, saw the announcement about the new Mega Arduino, checked with Coolcomponents to find they had stock and ordered one there and then. Checked my emails this morning to find a confirmation that the mega Arduino has been posted and is on its way.
Excellent work by the Arduino team and excellent service from its distributors.
