We love ours! Both LadyDi and I have the iPad Air (4th Generation) with 256 GB. They are as fast as the internet provider service we use will allow. I also have an older iPad Air (2nd Generation) that is significantly slower in a side-by-side comparison with the newer 4th generation iPad.
The iPads are our primary internet tool, even though we both have MacBook Pro laptops available when we need to use full computer software programs like MS Word, Excel, etc. And, for really high-end office work, we do have an iMac desktop in our home office.
Around here, the iPad is the real workhorse.
