I use one and am very happy with it. Best transfer speed are in Infrastructure mode rather than Ad Hoc. Even in Infrastructure mode NEFs will take a while to transfer. Somewhere around 15-20 seconds IIRC. My normal usage in my small studio is to shoot RAW+JPEG Basic and just transfer the jpeg to my laptop. The images are placed in a folder watched by Lightroom and are automatically inported and displayed. My portrait clients can then see all the shots and pick the ones they like.
WT-4A setup is a bit easier that for the WT-2A I used with my D2X, but is not very intuitive. Knowledge of wireless networking is really helpful.
