MacBook Air M4. Now can do internal + 2 external displays.

MBA 13" with M4 10/8/16 chip, 16 GB memory, 256 GB storage is $1000.
MBA 13" with M4 10/10/16 chip, 32 GB memory (max), 1 TB storage is $1800.

Based on how I've used my MBP M4, fan comes on when I run Handbrake (all the time), MacWhisper (usually), or 4K Video Downloader (sometimes), DDO with CrossOver (all the time). For gaming I think I'd want a MBP over a MBA. But now with experience I think a MBA (with no fan) would still be acceptable. A MBA would need a dock for more ports since I'd still need an external drive for media storage.

Mac Studio M4 Max. There's also a higher end with M3 Ultra which apparently confuses people but it doubles the cores and 60% more bandwidth more than makes up for M3/M4 gap.

Mac Studio M4 Max 14/32/16 chip, 36 GB memory, 512 GB storage is $2000. 1TB storage +$200.

If I was buying a Mac Studio the lowest end would be just fine. But I don't need a pro machine. A Mac mini would be more suitable:

Mac mini with M4 Pro 12/16/16, 48 GB memory, 1 TB storage is $2000 which actually makes that lowest end Mac Studio rather appealing.
