I've got an older Android tablet and never had a problem. My wife must have dry fingers or something, but she can never get it to work properly.
Usually you have a little manual telling you how lightly touching does something, as opposed to holding you finger down does something else, and dragging in different directions does some other action. And how to set up icons which are links to Apps or browser pages. And a bit of exploring lets you figure out where the content of your SD card or USB stick are (it's not as intuitive as Windows Explorer, rather it's a bit like mucking around with Linux))
After you've set up it's wireless settings (WAP key and the like in the settings), all you really have to do is set up a Google Account (preferably on your home computer), then go to the Apps section and find the Google store, click on it, sign in with Google Account, and check out the thousands of free apps and thousands of the ones you pay for. First things you may want to get are PDF readers, and free third party Office suites that let you open Microsoft Office files.
The only thing I've ever had problems with was e-mail. The various e-mail programs didn't find the right port numbers. I had to go into Outlook's Email Accounts, click on one, click on More Settings, then on Advanced to find the Port numbers for Incoming (110) and Outgoing (25), then put those numbers into the settings on the email program. Everything then worked fine.
I'd occasionally hit some problem - like my browser not being able to play a radio station I clicked on. Then it was just a matter of going to the Google store and finding a free App that played radio stations.
Beware of other free App sites. Most of the ones I've tried just wound up being full of annoying ads when I tried to use them.
What I like most about Android tablets is that they have a USB port.
