What have you ordered?
I actually ran the emulator for a couple of weeks on my desktop to see how well it works. In the end I thought "why not?", it's only $25 delivered.
Now it's here...first impressions are a bit mixed. The red/blue writing above the keys is very low contrast against the shiny faux-carbon-fiber casing. Kinda hard to read. The keys also have very little travel.
