..surely the 'best' hobbyist musician 'tablet' sweetspot for price/useability and features would be the Apple iPad Air (11-inch)... it's what most hobbyist musicians use, unless you intend to read sheet music, then the 13-inch version! 🤷
iOS is generally considered better for mobile music production due to its superior audio architecture and massive app ecosystem. Apple's CoreAudio framework delivers near-zero latency right out of the box, whereas Android has historically struggled with audio lag.
Class-compliant MIDI keyboards and audio interfaces usually work instantly on an iPad without needing extra drivers or troubleshooting.
..but at the end of the day, it's YOUR choice sir... 😊
