64GB will cost you $800 now. When you need it, it may cost half that, or less. And Apple was notorious for underspec'ing the maximum amount of RAM a machine could take - it was common for a machine to take double the Apple official maximum because the DIMM densities increased with time. Since the integration of the memory controller into the CPU this is less of an issue, but the soldered RAM means you're limited to the amount that Apple is prepared to give you, which until this model has been far less than the CPU actually supports - the 15" i9 could be spec'd to 32GB, but the CPU could address 64GB.
Apple's attitude to upgrading is to replace the entire machine. It's both expensive and absurd. I bought a 2008 MBP back in uni in 2010. I later upgraded the RAM and disk when I could afford to, and when I had reached the limits of what it had. That machine served me well for 5 years. There's nothing else on the market today I'd trust to be a daily use machine for 5 years straight.
Even the XPS 13s are more serviceable than their rival MBP 13"s. The RAM may be soldered on both but the XPS uses a standard NVMe SSD. It's saved me a few times already.
Not just the risk of data loss, but the inconvenience of restoring the machine is much higher. This means the only solution to restoring a modern Mac notebook is to replace the entire logic board - everything else may be functional except the storage, which is a consumable by most considerations, but now the entire board must be swapped. And if it's out of warranty, which let's face it, it's extremely likely to be, then you are completely and utterly stuck. You either have an enormous bill from Apple or an authorised repair shop (and Apple is notoriously cagey about allowing third parties access to their replacement parts) or you have to hunt down a machine for spares to do the swap yourself, and now with Apple's invasive security measures requiring communication with Apple's diagnostic tools to perform certain swaps, storage failure can render the machine entirely useless for months, if not permanently. Whereas if the disk was replaceable, just order one from the most convenient store, swap it in, restore from Time Machine.
The Function Key MBPs have a problem with their flash storage where they may randomly and unpredictably die, taking all the data with them. The fix is a firmware update, which also takes all the data with it. Fantastic, Apple, we bought six of those machines, and because the users are actively, y'know, using the damned things, it's not really convenient to tell them they'll be without their machine for a week while the service centre gets around to it, and then multiple hours of restoring their Time Machine backups. On the plus side, the SSDs in those machines are not soldered. Yes, they're proprietary, but it's something - if those machines suffer failure, I could grab an SSD on eBay and get them running again. It's almost worth the risk.
Sure, correcting typos, I wouldn't hold that against them. However, when they intentionally scratch out search terms for no apparent reason and show extremely vague matches, it's completely useless. I was searching for a specific error message that was causing my MacBook to freeze on login. Instead, the only two terms Google preserved were 'mac os'. First result was Apple's own page on the OS. Every result was entirely useless. Fine, if there's no actual result for this error message, tell me, but don't make me scan through a page full of irrelevant links and make me figure out myself why they're irrelevant.
Amen to that. I got to where I am as a sysadmin by knowing how to filter out keywords to make my search specific. Then Google throw all that away and decide for me what I want to search for. No Google, you don't tell me what to do.
I searched for an error message yesterday and Search removed 18 of the 20 keywords (they are all scratched out as 'missing'). The only remaining keywords were for the platform I had the error on. Thousands of results that were all completely irrelevant. I was completely stunned how something I rely on could suddenly do that. What is the point?
Google's monopoly has gotten to the point where they do not care how their products perform, just so long as the money continues to rain in.
