When I started remote billing back in 2011, I bought an ASUS laptop, for something like $329.00, because it was one of only two laptops at the store that had the number keys also off to the right side of keyboard, sparing me having to buy a USB plugin number pad. It is now 2016, and this dang ASUS is going strong, and has never given me any issues. I can't speak to their notebooks, but their laptops are the bomb! In the same time period, my husband has gone through two HP computers, so that is saying something, I think.
I have three different PM systems uploaded on my ASUS, and there are times when I will have all three open, plus various cloud-based EHR's, and it always keeps up.
