Hi, I'm learning how to use the iPad to create digital work for my business. My iPad is kinda old and I'm looking for an iPad Pro but I'm a little confused so I would like to know which one is the latest? There are so many iPads and iPhones out, I can't keep up with what's new. There's iPad, iPad Pro- there's 10.5" and then there's 9". And also is it a good time to get an iPad now? Usually I don't wait for new releases because often the upgrades are minimal and the price is way exaggerated but (again) since I don't keep up, I don't know whether waiting would be a good option. I bought an iPad 10.5 cover by mistake recently so was hoping the new one would be a 10.5" since the cover is expensive and pretty decent. Any tips?
