I don’t mind paying for RustRover for commercial use as an individual but only bundling it with the all products pack sucks. I’m not paying $300 for RustRover.
I have PyCharm 2023.2 with the deprecated Rust plugin and it works great. I don’t think that’s restricted to Non-commercial use. Also VSCodium exists with the Rust Analyzer plugin so that’s another alternative
If this had cellular connectivity it could actually be a pretty cool phone. The battery life is probably good too
