Thanks for the input guys, I had heard that the gen 1s and 2s were not so great, but supposedly they fixed things for the gen 3s. I'm bummed to hear the dock sucks and wifi drivers don't sound great... I feel like since IBM sold off the thinkpad brand, it's been going down hill in quality :\
I'm mostly interested in the x1 gen3 for it's light weight and thin-ness, before this I was looking at a UX305 from ASUS, but because they're passively cooled, the backs get up to 110*F, and I'd rather not roast my nuts. 8gb is worth it then? Sucks that it's soldered onto the board, I assume this is both a space savings and engineered failure to get you to buy a new one
Also, I've been shopping on Lenovo's outlet, trying to find a better deal than paying full price.
