On the hardware side is their HP Pro Tablet 608. It's an 8” tablet with an Intel Atom-Z8500 processor, 4 GB memory, 128 GB of storage and a USB-C port. Should be out in August for $480.
Several of their newest PC’s support “dual-array microphones” with improved noise-cancelling software for better voice control with Cortana.
On the software security side is a cool feature called Sure Start. It checks the BIOS before boot time and if it finds that the BIOS has been modified, it replaces it with the original. A similar feature is available in Windows Secure Boot – but that just refuses to boot if it detects a problem. Sure Start will be included with Elite notebooks and ZBooks.
If you're looking for a new PC for home or back-to-school, several of the new Windows 10 HP's will be available for purchase ahead of the July 28 release date so that they can be delivered by July 28.
