The xps 15 is a good alternative. Windows 10 is a great operating system, and Dell makes some killer hardware.
I have had a few bugs, but they have always been fixed promptly via updates. Just like my MacBook Pro.
I won't deny the new MacBooks are nice and tempting, but the limitations and price are rather offsetting.
If to wait for a deal, like I did (2 months ago, via slickdeals) you can get a great deal on an xps 15. I got a the newer model with 4K, i5, dGPU, 256 nvme ssd, and 8gbs ram. The ssd and ram are upgradable. The laptop has USB c, USB 3, so csrd slot, etc. The trackpad is as good as I have used on windows, and equal my experience on my 2015 MacBook Pro 13 retina.
I got the above laptop for $910. It was from the outlet, but was brand new. Came with the standard 1 year warranty (will send a tech to you house), and you can upgrade the warranty if you wish.
I mention this because, again, the new MacBooks are tempting. But what windows offers is also great, and in some areas superior. But the price is the kicker. To get a 15in MacBook Pro starts at $2399. That's a big price difference, no?
