Is NS WMS still bad? Or is it something quite close to RF-Smart now?

It has closed the gap quite a bit - but if you need any sort of customization I'd lean RF-Smart

That's good to know. By the way, do you have an idea as to the price difference?

It is not a WMS. RF-Smart isn't a WMS either

Oh, what are they called then?

Don't think there is a generic naming, but something like "hand-held extension of ERP"
