Look at the Ultrabook models from top tier manufacturers like Lenovo, HP, and Dell. Focus on their "Pro" or business grade models. There you will find quality models that are thin and light, yet still offer features like touch screens and expandability that Apple does not. Beyond that, you will have a huge choice. Do you want an 11" screen model for extreme portability, or a larger screen for productivity? Do you want a laptop/tablet hybrid, or a more traditional form factor? Do you need 32 GB RAM, high end video card, and an I7 processor, or is long battery life more of a concern? Laptops always involve trade-offs, so you need to decide which features are critical for your needs, then look for a machine that fits. That is where Windows machines have the advantage, in the wide variety of choices available to fit every need rather than Apple's one size fits all approach.
