hi folks I have read far and wide in trying to decide whether to purchase the iPad Pro as my next Apple device. As a background - I have an Apple dominated house, with Airport running my Wifi, a 2011 rMBP, wife has an Air, Apple Watch, iPhone 6, iPhone 6+, 2nd Gen iPad, iPods etc etc. The reason I have to buy the iPad is for productivity. I'll be using it for light work related activities as well as consumption of content. I have some particular questions on what I'd like to use the iPad for, and hoping you can assist me with - possible or not possible type answers... 1) connect external SSD for back up of data, photos, transfer of files etc? 2) ability to download high res RAW images from SD card from my Canon prosumer and retain these RAW formats for later user and distribution (rather than convert to JPEG or GIF or some other transitionary lower res format). 3) any ability to use function keys when using Excel? I know there is no support for VBA, but what about advanced formulas such as arrays and indexes? 4) any ability to be able to produce content such as websites and blogs? 5) ability to use trading tools such as ICE or X Trader to view/execute in the market place? Any assistance is appreciated as ever.
