as long as you don't need any of the features of WCF you shouldn't of course (though I think webservices become an obsolete technology).

As soon as you run into edge-cases with authentication, compression, binary formats etc you'd have to use WCF. I think many use WCF "just in case" they need those features

Considering I've went from http to tcp services a number of times for improved performance, and you can simplify WCF clients a LOT via convention, it really isn't that bad...
