I just played with one today. R&S themselves told me the firmware is, umm,
They wanted to send me one but were embarrassed to send it in it's current state
I hope R&S will eventually get the implementation right. Given their reputation, I am counting they could deliver. Even if it is expensive now, if it picks up interest in the market with its compact form factor and R&S badge, hopefully it could trigger "inspirations" for competitors for the next generation of scopes - cordless handheld. And with healthy competition, there's only one way for the price to go - down. Although it can be argued that handheld scopes have been existing in the market for a while now, the implementation has been mostly well....unappealing
I can relate this with power tools too. With the advent of Li-Ion batteries + brushless motors and after having had one, I find it hard to go back to corded tools anymore. Of course unless you specifically need the power that only corded tools could offer.
