Are there any alternatives?

There are a few alternatives to the Samsung M8:

　　$4330 Samsung M7 — You get basically everything you get with the M8 with the M7, including the apps, a 4K resolution, and a 60Hz screen, for $370 less. However, the stand is much worse without any adjustments, and you don’t get the magnetic webcam.$766 Asus ProArt PA329CV — It’s a bit more expensive than the M8, but it offers much wider color coverage and accuracy for content creators. It also includes a 90W USB-C hub.

How long will it last?

Assuming Samsung will continue updating its TV operating system, you can use the Samsung M8 for several years without issues.

　　

Should you buy it?

Yes, but only if you need the various features the M8 offers. Solely as a monitor, there are better options for less. The M7 is a great alternative, too, assuming you don’t need the webcam and can pick up a monitor arm.
