After many years of happily using DLink hardware, this will be my last router. I've had problems with my DIR-655 since FW 1.02 (won't allow some B clients like my old iBook to authenticate) and now these changes to a whore philosophy; no thanks.
That's not necessarily a DLink issue - I've got a client with a Powerbook that will not authenticate on any of three wireless APs setup with WPA-PSK/TKIP. The three routers are two Netgear models and a Linksys WRT54GS v2.2 running Tomato. This same powerbook fails at another location running Cisco gear configured with WPA.
All that being said, I'm not much of a DLink fan. They have had some very good products along the way, but they have been hit-or-miss over time. Most of my network is made up of Netgear stuff with some Linksys sprinkled about.
