I also think on at least the Android front Samsung has consistently demonstrated the ability to make phones with both SD cards and removable batteries for years without compromising form factor. The S3 / S$ / S5 and Notes 2 - 4 were all extremely thin profile despite supporting removable batteries.
This is just misdirection to try to persuade people its a good thing to remove choice. It is not, it costs basically nothing in manufacturing or size to make the battery / ram / hard drive removable, and the only reason Apple / Dell / Samsung (now) / every other Android phone manufacturer does it is either to rip you off on overpriced battery replacement or drive planned obsolescence to make you buy more shit you really wouldn't need if you could just replace your damn battery two years later.
A year ago, I wasn't sure how much longer my ancient (but still functioning!) 2008 MBP would be going on. So I went shopping. Found the same tradeoffs Marco mentions here: I didn't like the sealed nature of the newer offerings (and also, AFAICT no screen density can make up for the inexplicably missing matte displays).
I ended up buying a used 2.6Ghz i7 8GB 15" matte MBP instead of anything new from Apple, though.
About the only complaint I have is that Mavericks seems neither as stable or as well-performing as Snow Leopard, which seems to be the last time Apple released an OS that was a strict improvement over previous releases. Too bad it's no longer safe to run given the state of updates.
It actually runs faster now than it did with the stock HD and Mountain Lion! Granted, I'm not doing a lot of heavy computing with it. For web surfing and the basics it still works great.
Which is a shame because OS X is a nice operating system. I would like to use it.
EDIT: and most importantly, more battery chemistry per weight. Safety requires that serviceable batteries are enclosed in rather substantial cases whose internals are non-user-serviceable. Apple "cheats" by making this case the entire laptop, rather than a specific battery module.
