1) Double Layer are more expensive still but are coming down in price as will Lightscribe media once more of it is adopted and its production costs are reduced .Just like lowspeed media like 4x is getting really cheap .
2) A firmware upgrade for 2x Lightscribe is due out in July according to HP
3) This is a problem with Nero not upgrading thier Lightscribe Host software .Surething has provided a upgrade that fixes the LS DVD disk compatibility problem back in Febuary when LS DVD media was'nt even availible in the Retail Channels .
4) HP has promised and is supposedly developing colour Media and all that is needed is a firmware/software upgrade when the colour disks become availible .It is not known if the media will be coloured or if full colour printing will be an option .I think the media will be couloured .
To the original poster lookaround for the BenQ and HP 640i they are the same drive and can be found for less than $100 .I have a HP 640i and it crossflashes with every availible Lightscribe firmware out there .Wallmart has the HP drive for $99 and Newegg had it for $99 with free shipping .
