I am on Verizon and am looking at tablets. The productivity is the main reason. I spend a lot of time in my truck or on job sites. I need to keep up with reciepts and invoices on every job. Right now I am using excel spreadsheet to do that. Does excel work on any of the tablets. I also need to download documents from the tablet to the server in the office. Job Notes, pictures, the ability for customers to sign documents on the tablet, email are all important items to me. I have no problem smacking a lippy subcontractor or crawling into a shit filled crawl space but technology is not my strong suit. Any and all advise is appreciated.
