That all being said, Scott's view on company not providing a laptop is extremely unusual in US. I've never come across a position like that.
Although, @scottalanmiller and I would never work the same type of jobs. I prefer to be an employee of a company vs being consultant or contractor. I have my reasons for it, and @scottalanmiller and others on here have their reasons why they like consulting.
I would never consider or accept a job where I had to provide my own computer. I also, think it's ludicrous to be an IT employee and not have your own personal computer. It just shows that computers aren't really part of your passion. If I worked first mate on a fishing boat, I don't need a fishing rod for my job. But if I didn't have one at home, that would be an extremely weird situation. It's not something I'd ever ask in an interview because I could just tell by talking to someone of they are passionate about IT (or fishing). I would never have to even ask them if they had a computer (or fishing rod). As @scottalanmiller mentioned, they would be extremely lucky to make it to first interview, and would never make it to second.
