Now we got 951Ui-2HnD and 951Ui-2nD. And the old 951Ui-2HnD looks slightly better... 128MB of RAM vs 64, more powerful WiFi and slightly wider range of receiving power... versus 650Mhz newer processor at lower cost.
But, of course, this model replacing the 951-2n...
Still waiting for hAP ac though.
