I have to agree with TOALAN!
Most of the time we get in troubles just because we forget to think in terms of hardware/software relation.
Probably we forget sometimes that each designs may need a different aproach.
YES, PBP looks easy, it has good features built in, the support is very good, comparing with similar software I will give it an 8 (in a 0 to 10 scale - giving it a 10, probably Melabs would stop improvements)
