Just thought I'd pop in to tell you that the WH1409 seems to be quite good, so far.
Here's a picture of it compared to my Intuos Medium and Large, it's not a great picture and the angles might skew things a little bit but hopefully it gives you some kind of idea of the size of both the device itself and its active area compared to a few other popular tablets.
I've had no problems with it thus far, but one of the users on my board remarked about having some problems with the wireless feature ( >>>/loomis/2086 ). I haven't used this feature enough yet to comment one way or the other but I'll definitely keep you posted if I run into any problems.
Personally I'm very impressed-I'll give it a while longer before I outright "endorse" it, but functionally it's very competitive with my $500 Intuos Large. Should fears about reliability be proven baseless, I'm confident it will stand among the best traditional "desktop" style tablets available, and easily the best for the money.
