for 3K you could look at most of the premium brands and from a hardware point of view, I'd say you have a good chance of finding something that suits your needs. Dell XPS 13 are popular and can be shipped and supported with Linux out of the box as well as Windows. XPS 15 can be an option if you're ok with some added weight and want more power. Lenovo T-Series have been around for ages and generally have quite robust hardware. There's also the Carbon X1 if you want something lighter, or the Thinkpad P1 if you want more power. HP Elitebooks - Similar to the other two these have a good range of options and good hardware build generally. On the Microsoft side there's the Surface Pro's and also the surface book, which is very pricey but again has some nice hardware. Of course all this depends on what you're looking for from a laptop, what is "worthwhile" is a personal judgement :)
