I have touch screens and find it very useful. My thoughts are if you have a budget now, get them now because you may not have the budget later. Also if you start with touch screens you will become accustom to them and will not have to relearn a new habit (
mouse vs touch).
You've had the
express, most everything you are used to is there, some under different names, but there is so much more. Things like -
cue 20 go vs go to
cue 20 enter, groups are only channels not values, your playback
wing is way more powerful, and magic sheets do so much more than just a lighting
plot ( you can have multiple sheets though). Don't stay with the old, push yourself to learn new and faster ways to get where you want.
You can down load the off
line version, setup your entire new
console with patches, groups, subs, and the like. Save to a USB as your standard rep show and then you can load it in the day your new one arrives. Also you can use the off
line to watch the tutorials and then try it out. Two laptops side by side is helpful so you don't have to flip windows from off
line to the tutorial.
Search CB for
ION topics, I find them helpful.
Enjoy
