Well My testing is over after tonight's Dinner music gig,and as suspected a tablet cannot compare to the navigational needs I need under pressure on stage period.
Searching for songs, lyrics, etc, is a nightmare when you have thousands of files to go thru while your playing.Scrolling with your fingers isn't gonna cut it at all vs a laptop keyboard where you can keep multiple windows OPEN at the some time,and find a song instantly with by just pressing a letter button.
So my trials are over,......The laptop remains KING on MY stage in a live situation for sure!! .....
I will use the tablet for my personal pleasure off stage.
Carry On
