I think you’re misunderstanding which ramp I mean. Looking between the wheels of the white car, it looks like there’s a ramp the goes from the parking lot up on to the sidewalk. The white car would prevent a person using a wheelchair getting onto the sidewalk.
I wouldn’t wait that long in the hope that Google release another Pixel tablet and that it then fixes the issues you have with the current one. IMO there’s too much risk that either they don’t release it, or they don’t release it at the time you’re expecting, or it doesn’t change things you care about, or they change the price/features.
I’d say buy the best (/least worst) thing you can actually get now.
