it is a very good software actually, very powerful. it will never be like real life sculpting but it is a very realistic approach. it does not need a very powerful computer to run (ram memory is the most important thing actually, 4gb will do. it has everything needed to create 3D artwork for digital media or for printing purposes, it is not extremely expensive as maya or 3dsmax (autodesk software is around 3000 usd and zbrush is only 699) and every new version or update is free once you pay your license. some of the cons is that with every new realease (often) there are things that stop working from time to time or courious bugs but they are quickly fixed for next release. it also has illustration and reder capabilities and compatibility with other softwares like photoshop or 3dsmax. for me it is the best 3D modeling tool there is.
