What can i say...i swore i would never stop using vinyl but after completely trashing my back from carrying crates i had to give it a try. The best way I can describe Serato is like when Nintendo came out and Atari was a wrap, I never went back to spinning vinyl on a consistent basis because there is no technical comparison to what you can do on Serato. Serato changes you as a DJ for the better because of all its capabilities(looping, internal/relative modes, cue points, etc.) and every new version they come out with has even more new features one of my favorites is instant doubles.
Like it or not, vinyl is dead. Serato is the next generation of DJing. No longer is it necessary to carry around massive record collections to gigs. All you need is the Serato kit, some turntables, and some mp3s, and the party is started. This is pretty much the industry standard amongst all of the popular club DJs like DJ AM, Spider, and others that dominate the Vegas and Los Angeles circuit.
