Now that it's unveiled its next-gen Ultrabook, Dell's taking the opportunity to refresh the machines it's already got. Starting with the XPS 12 convertible Ultrabook, the company is adding an NFC chip, Haswell processors and a bigger battery (50Wh, up from 47Wh). Between that CPU change and the enlarged power pack, Dell says the system will now last up to 9.5 hours on a charge -- more than three hours longer than the OG version. Fortunately for you, the starting price is staying put at $1,200, with shipments beginning July 9th in most regions.
Moving on, the XPS 27 all-in-one is stepping up to a 2,560 x 1,440 screen with improved brightness (350 nits vs. 300) and a wider color gamut (99 percent, up from 72). As you'd expect, Dell also swapped in fresh Haswell processors and a 2GB, next-gen NVIDIA GPU, along with a Thunderbolt port, TPM and Dell's ProSupport service offering. Finally, the machine's getting a bigger storage option: a 2TB 7,200RPM HDD paired with a 256GB SSD. That's available today for $1,600 and up -- the same price you would've paid for the last-gen model with a touchscreen. Finally, Dell replaced the XPS 8500 desktop tower with the XPS 8700, which brings Haswell, along with four HDD bays, up to 4TB of storage and up to 32GB of RAM. Additionally, the SSDs offered now include Intel's Smart Response Technology. That's available today too for $700 and up. Happy shopping!
