back up a whopping 9GB of data on a single disc

The one problem for now, but on past trends will be only temporary, is the
significant difference in cost between singles layer and double layer
media. For example you can currently buy, here in the UK, good quality 8x
single layer media for less than 20p (about 36¢) whereas the cheapest dual
layer is around GBP3.5 (about US$6.5).

Expect to see dual/ double-layer DVD burners in just about every
desktop PC sold in 2005, even in budget systems. These drives let you
copy full DVD movies with no loss of quality, back up a whopping 9GB
of data on a single disc, and even plug a DV camcorder directly into
a drive to burn DVDs.
