I bought a Samsung Tablet and after six weeks returned it. I found that I didn't need it as much as I thought. I use an Excel spreadsheet for cues and prompts. Column 1 is the script page number. Col 2 is the character name, Col 3 is the text, col 4 is the Cue/prompt. Once we get everything finalized script-wise, I remove the Page column and add a column for notes, etc. During initial rehearsals, I will have a blocking column instead of the cue column. You can duplicate a sheet and label a tab for each rehearsal day and change blocking, script at will. That way if the director says what did they do yesterday? You can tab over and find it relatively easily. You can do all that on a tablet, but I wanted it for the pen feature on the "Notes" app. It wasn't as helpful as I thought. A relatively new laptop will get you there for less money.
