On desktops yes, but on laptops Linux isn’t as rosy.
The rise in Linux is due to Valve and Microsoft being a major failure when it comes to windows.
Similar in MT yes but not similar in single threaded performance. Plus the M3 Max has great encoders and decoders which AMD laptop APUs have but not as nearly as quick as Apples. There’s nothing like the M3 Max from either AMD or Intel in the laptop space.
The M3 Max has 16 channel memory and a 512bit bus you won’t get level of bandwidth with upgradable memory in a laptop form factor.
With AMDs upcoming Strix Halo the RAM will be soldered up to 128GB but this means higher memory bandwidth and the GPU can access most of that RAM. This is a mix between the Pro and Max chips. But I doubt it will as efficient because they the desktop dies which are idle hungry.
Where Apple undoubtedly price gouges in the SSD department.
Apple also doesn't make servicing easy. MS's latest laptop got an 8.5 I think from iFixit.
I like things to last a long time. I think that is better for everyone. I have been happy to spend much more to buy something with longevity built in. But now with Apple, they punish the user who buys a bigger drive and more RAM which will extend the life of the computer due to a larger drive doing less work and hence lasting longer.
I'm hoping for T-5 ports as this will lower the need for having over a 2 TB drive IMO. The alternative for me is to buy a cheap and cheery slower mac without much capacity and be prepared to chuck it away. I guess Macs these days underneath their casings are all really notebooks or phones. Apple wants them to fail earlier than their previous units which had upgradable internals. I noted an Intel marketing person (maybe a senior exec or President or something) showing an Ultra CPU with soldered on RAM attached and boasting it was 30% faster. As our devices become more stamped out sealed items I guess all big companies will design out long life by stopping serviceability.
