The Dell Latitude 13 (7370) is the business version of the XPS 13 [1] [2], although for some strange reason Dell decided to swap the Core i5 and i7 processors in the XPS for Core M5 or M7 CPUs.
If I had to guess, it's because they're betting that for business users buying an ultrabook-style laptop, the battery life you gain with the M-series is more advantageous than the extra processing power.
In two previous jobs I had Latitude notebooks. Both were pretty old at the time I was using them, so the battery was pretty much unusable. Besides that, they were working very well. Reliability-wise, these things are totally worth the price.
