Dell Systems Developed by and for Developers

That's too bad. My m6800 is working great for years now and I used a smaller one at work for 2 years, without issues.

The Inspirion line is not equivalent to Dell's Precision workstation line.

One difference is the warranty (US). Precisions come with three year next-business-day onsite warranties standard (and are upgradable from there with more years and better response). Other differences include the availability of Xeon CPU's, ECC RAM, system certification, and 'professional' GPU's.

Battery life on the Precisions tends to be pretty weak and weight and bulk high. These will tend to work against or rule out a number of use cases. On the other hand, raw compute is substantially greater and that's a benefit of the tradeoffs.
