?? Not sure what the meat of your question is, but the simple answer to the topic you posted is...could be. It is really up to you.
I am using an older Nostromo now (version with the Razor name right after they bought it from belkin). It works, it is not bad, but I would like more buttons like the Orbweaver has.
For using the XIM I prefer the smaller game pad over a full size keyboard.
You may feel differently.
