Oh yes I forgot to mention Documents to Go! I use mine to write contracts and proposals plus the spreadsheet for lots of things. Playbook is a business machine.
I forgot that too - how could I forget that. Nothing beats having Word, Excel and PDF right on your device :-). I’ve been carrying a wine list for years - notes on everything we’ve tried. I pass around recipes using Word on my phone. Actually all my best recipes are on my phone. We keep customer information in spreadsheets (passwords, IP addresses, etc.). I always have all that information handy because I have Excel. Love Documents to Go.
