I've been displeased with Dell products for the past decade+, with multiple copies of personal, business, and pro/engineering-class laptops. Their recent and current products are solid, and dare I say the best on market.
Also have a Lenovo Thinkpad now that is good in many ways, but is also poor in many ways.
Those 2 along with Microsoft Surface (if they ever get their port selection right) are the only 3 credible selection in the Windows world, IMO.
Depending on what the new Mac look like though, I just might be back in the warm embrace of Apple.....
