The XPS cases are more durable than the latitude
Eh… Maybe? I worked plenty with Latitudes but never even used a XPS, but Latitudes aren’t bad build-wise. There are entry-level Precisions without dedicated graphics, and at least here in Germany they seem to be cheaper than comparable XPS-Laptops.
I know that the XPS is meant to be a prosumer product but I think the comparison is fair either way, mostly because you can actually buy both as a consumer. Dell doesn’t lock you out from buying a Latitude if you’re not an enterprise customer.
Latitudes aren’t sold at big box stores, that’s about the only difference the target audience makes to the general consumer.
