I pre-ordered mine yesterday, and the site indicated that it should be shipping today. We'll see. I'm going to pick up a Maxtor 5400 RPM 120 Gig drive this weekend. I'll be sure to let everyone here know how well it works out once I have all the parts and pieces.
update! update! update!
You wanted an update, well here it is....
My hdloader is still on pre-order. It hasn't shipped yet, but according to the site, they should be shipping tomorrow (something about having the Discs, but needing to wait for the documentation and case covers, which are somehow more bulky *see below). I did pick up a 120 GB 7200 RPM Maxtor drive at Office Depot for $80 Tuesday night, so that's all ready to go. Fortunately, the shipping is FedEx Air Express, so I should get it by Monday, hopefully.
*My guess is they sent an ISO image or Gold copy of the disc, but are shipping pre-printed manuals/covers? Why not send electronic copies of those as well? Just license out the ability to manufacture and print copies, as long as they meet certain specs, for 25% of the retail cost per copy sold.
