Hi!
One of my perpetual gripes with many of the EDA/PCB design tools I have tried over many years is the subject of user manuals, not only are makers like Altium trying to con you into paying up to (and over!) £1000 for compulsory maintainence, they have the nerve to do away with basic manual support as well –AD hasn't supplied any printable bookwork since v.14, Orcad won't let you get at their books from their website without costly maintainence, Vutrax is the same, I've never seen any books for Labcenter Proteus, and I've a nasty feeling the other vendors are going the same way!
Surely, even if you only request a time or feature limited trial version, you ought to be entitled to some basic bookwork included in the disc/download, especially when you consider the price of some of these suites?
