My priorities as an educator were for the kids to be able to jump up, lay down and whisper across the room. I also wanted to make sure the devices were safe (for small ears) etc. I wanted the kids to feel as much as possible like they were in the room with me. I didn't want to create an experience where kids had to sit still at their desk or strain to see or hear.
As a teacher, I prefer when kids use a mac laptop because when they screen share or use an app their image does not disappear (which gives less of an in-person feel). I like that they can open multiple windows, so for example, I can be showing them one app, while they're working independently - and I can see their face when they're trying to work independently. Otherwise it makes me feel less like I know what's going on with them.
The big downside with the chromebook is that it doesn't support a lot of amazing apps which are so great for learning, especially at a time when giving kids a fun app they can use independently is a big support to the whole family.
As much as I like a laptop, a lot of our parents prefer the ipad, however, because kids are a bit more free to move about the house. Also, it's considerably less expensive, which makes it easier for all of us to help keep access to our group equitable. We do our best to sponsor any child who can't afford our group but wants to join and we're trying to make this as scaleable as possible so we can offer it to more families everywhere.
Ultimately, this is the winning combo we went with.
Ipad (most recent version or possible)
Wide lens (so kids can move around) https://www.amazon.com/Xenvo-iPhone-Camera-Lens-Clip
Airpod pro (by far the best for sound and most comfortable) https://www.apple.com/airpods-pro
Ipad stand (so kids aren't constantly looking down) https://www.amazon.com/Gooseneck-Tablet-Mount-Holder-Bed/dp/...
Hope this is helpful. Let me know if you have any more questions about our findings:)
