I understand your concern based on some of the points above, but in regards to the R&D into new products, I'm sure you've seen all the information and discussions on here about Cyberbiz? Their new security offering for small to medium businesses?
Their staff and operational costs have certainly gone up, but I believe this is to ensure that they have adequate measures in place to service new customers that come on board as a result of the rollout and (potential/hopeful) increased uptake of the Cyberbiz product.
You may have also seen in the latest 4C that their cash reserves increased in the last quarter to $1.65m, albeit by a small amount. And that they moved a bulk of these reserves to term deposits.
Certainly keen to hear others thoughts on the above.
