I dont really reccomend going to a touch screen for live shows…and here is my thinking…
1- Another Piece of expensive equipment that you have to carry around thats not so portable…
2 – DJ booths are already cramped as hell already
3 – Touch Screens are really not more intuitive than actual Buttons and Knobs, Bigger Chance of making mistakes on a touch screen
4 – What exactly would you want to control with it that you couldnt control with an additional controller?
5 – Ipads dont really have a learning curve. Especially with Lemur on the OS.
IMO Windows 8 wont be really useable for at least another 6-8 months. I have read that Windows 8 is horrible for gamers…and that makes me feel that it will be bad for us DJs as well. Windows 7 is actually pretty dang stable now…and it does everything i need for DJing…so if it aint broke why fix it?
