After promises by Google of a June 15th launch date, both Computer World and 404 Tech Support have reported that Acer Chromebooks are nowhere to be found, and Samsung's Arctic White 3G is the only model available for order while the rest are still listed for pre-order.
Did you pre-order a Chromebook that isn't the Arctic White 3G Series 5? If so, have you received any type of notification as far as when your Chromebook is expected to arrive?
UPDATE: I just received this email from Best Buy. All Samsung Series 5 models are available for order, but this means that anybody expecting to receive their Chromebook by tomorrow (like myself) will have to wait a few more days.
I have a hard time believing that company got an injunction to stop the sale of these things... If they did, I think it would be all over the tech blogs by now. It's more likely that there's just a shipping or manufacturing delay.
