While not the 2018, I have the 2017 5th gen iPad and it has been one of the best, most cost effective Apple purchase I’ve made. I use it every day for the Internet, reading, some streaming, casual gaming, and light email/office work. I also use it when I travel and don’t need a computer with me. The LTE connection has come in super handy for me on many trips.
It has also been rock solid so far. No pencil support, but that’s been okay for me as I likely wouldn’t use it anyway. I think this base, budget iPad is one of Apple’s best, most reliable offerings.
I’m looking forward to seeing what they do with it in March as I might upgrade. I usually keep my tablets much longer but if Apple continues to offer the base model at a reasonable price I think I might make the upgrade after two years with the 5th gen.
