I have a Yamaha CRW-F1. It's possibly the finest overall CD-R/W ever made (i.e. -- Audio Master capability, large buffer, etc), but I have no use at all for Disc T@2.
This newer way of doing it on the label side could also be a damn slow process just like Yamaha T@2 writing is -- actually worse -- because you will have to pull the CD-R out, flip it over, then re-insert it and write out the monochrome image over that large area. So, if you don't want to wait 15 minutes or more, you'd want to try to keep your artwork relatively small if this is indeed the case with speed.
HOWEVER, if one of these manufacturers gets smart, they could install a second laser, or a pair of (or more) lasers ala Kenwood Zen-X, on the topside of the unit and start writing the label side at the same time the data side (below) is written. The label side writing may very well have to be written at something like 1X up to 4X, or at the equivalent exposure by writing multiple passes at 52X to attain good visual contrast.
