I did get the USB adapter and it all works with my DSL connection (I did have to purchase a router).
I did it for the experience and to access the style files that are for sale.
The positive side: the ones I have purchased are very good; the negative side: 1) It is almost impossible to judge the quality from the demo, 2) There are too few styles, 3) The cost is much higher than most users expect. The ones I have are probably worth the price, but I would have downloaded many more (the process is a bit cumbersome, especially the first time; do not be too discouraged) if they were more reasonable.

Michael
