Are there any alternatives?

There a number of solid Windows all-in-ones out there, such as the HP Envy 32. It’s much cheaper, but it can’t compete in terms of performance.

　　The Surface Studio 2 is a beautiful all-in-one with an ingenious floating hinge, but it’s a severely underpowered machine, relying on a laptop processor and outdated graphics.

　　Lastly, the iMac and iMac Pro are now closer in comparison than ever before. The iMac’s 10-core processor is more affordable than the 1o-core iMac Pro, and uses more up-to-date Radeon graphics. Of course, if you want the ultimate performance and price is no concern, the 18-core iMac Pro is hard to beat.

　　

How long will it last?

The 27-inch 5K iMac should last you at least over five years. It’s incredibly well-built, and Apple has committed to supported Intel-based Macs with updates, so no worries there.

　　Apple, of course, offers the best warranty and customer support of any computer hardware manufacturer through AppleCare, which covers hardware repair and includes and 90-day complimentary technical support. The initial limited warranty is just one year though.

　　

Should you buy it?

Yes. If you can hold off until next year for a redesigned iMac, more power to you. In the meantime, the 27-inch 5K iMac remains the best all-in-one computer you can buy.
