You can't upgrade automatically, but you can download and install Windows 11 using your Windows 10 license key. It will work fine. They just hate you.

Since everything is dumb it will likely cost more than the 24GB RTX 3090.
Update: Actually, come to think of it, this isn't possible. There could be a 20GB 3080 - non-Ti - but the bus width of the 3080 Ti is the same as the 3090 and it would have to go to 24GB, which would make it 98% of a 3090. Kind of pointless.
There are no good small Android tablets available. It's not even that they're overpriced; there just aren't any. At 10" and up there are some options, mostly from Samsung. I'm pretty happy with my Lenovo but I'm not sure it's still available. With things going randomly out of stock all the time in Australia anyway it's hard to say.
