I don't care if Google reinstate them. I'm staying with Huawei regardless of the cost to myself partly because they make great phones and partly as a protest against the USA. If it ever comes that far, I'll just use my Huawei as a camera. It would still be worth the money.
$900 is still far below the price level of even the bottom end range of interchangable lens bodies, never mind body+lens.
The bottom end for such bodies is around $1500. Add another $100 for a low end lens, or ~$1000 for a low end Leica level lens to match the $900 for the huawei.
You are essentially getting a free phone and camera with a (slightly worse than interchangable-level quality) leica lens with the P30.
That's not accurate. You can get a Sony a6300 with a lens on amazon for $850 right now. That will get you a much better image, with a lot more flexibility. If the P30 is your phone then it's a fantastic camera and certainly more than good enough for most people. But if you're just getting it to be a camera you're wasting a bunch of money on features you won't be using.
