The new Dell Venue 8 Pro with the equally amazing and new Intel Atom processor Z3740D which IS a 64 bit CPU so why does this hardware only run 32 bit Windows 8.1? That is because Dell wants to use Microsoft’s new Connected Standby standard which (today) only works with 32 Bit Windows 8 and Windows 8.1 . “Connected Standby” is Microsoft’s new ‘power on in less than 300ms) standard.

In case you think this is just a lightweight piece of garbage… check the tech and think again. Don’t get me wrong, you are not going to confuse this with your $1000 Ultrabook, but it the CPU is pretty sweet with 4 CPU cores (all real CPU’s, no Hyperthreads, 1666Mhz RAM and HD4000 video).
