Of course, your first decision(s) will be 16, 32, or 64 GB & Wi-Fi only vs. also 3G - plenty of advice already on those topics here, so please do some searching.
Then of course will be choices of Apps wanted/needed and a bunch of possible accessories, e.g. case(s), keyboard, camera connection kit, etc.!
Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
