What do they say? Quickly browsing that site, I find a report that the M1 isn't faster than 98% of the laptops (been there before) and that it doesn't work with eGPU, but no reviews.
You should try Google once... Bought a brand new Nexus 6p to get myself into a rock solid ecosystem that set the Android standards. 2 months later, Google cancelled the whole Nexus brand and all updates. Planned obsolence is a fact, but Apple isn't the worst offender by far.
Yes Peter, I know, and the more you get out on the edges of the Android hardware side, the shakier the ground. From my perspective there are only two serious players in the Android phone space, those being Samsung (big name, big money, new big commitment to a two year OS support for all new purchases), and Oneplus. Huawei (Chinese and under an embargo due to surveillance chips in the phones and tablets), possibly LG are players. Even though Xiaomi and Oppo far outpace LG, Motorola and Sony, I don't count the two former because they are Chinese with zero US backing. As such neither Huawei, Xiaomi or Oppo has to back their phones on any level. This game is won or lost by Apple at this point, and I don't believe 5G is a service that will tip the scale.
In Apple's favor are the A14Z and integrated memory, and familiarity of brand. Against Apple is the retro 6 year old iphone 5 styling, the 60hz refresh rate, the lightning port, MagSafe (I've only read a few positives, the rest have been horrible), weight and battery size.
In Samsung's favor are the Snapdragon 865+ (while it benchmarks lower than the A14Z, a side by side app launch and real time response shows the Snapdragon is just as fast), the camera(s), the 9ms pen (on the Note Ultra) the 120hz refresh rate, 12Gb RAM, the much larger battery, the open app environment, $300 lower acquisition cost, and always on display. Against the Samsung are a non-unified platform, the MASSIVE camera hump, the distance between updates, and automotive integration (I freaking hate Android Auto, but if I have to go back to Android, I'll suffer through the pain).
As to what Slashdot patrons have said, you'll have to dig. I stumbled upon a "why we are leaving iPhone" thread, and it, as expected with the title, was not pretty. The biggest hit the iPhone Pro Max took was BT connectivity to various buds, and the screen flicker.
