Wilcom has been touting these miniature handhelds for quite some time now, but the D4 has yet to get a Stateside release date…until now. The diminutive UMPC sports a full version of Windows Vista, running atop a 1.33 Ghz Intel Centrino processor, 40GB hard drive, 1GB RAM, Bluetooth, 802.11 b/g, and a 5 inch WSVGA touch screen. Pretty appealing stuff, but running Vista on a 1.33 Ghz Celeron processor with only 1 GB of RAM? Sounds like a potential train wreck to us. Regardless, if this is something you’re after, you’ll be able grab one from GeekStuff4U on June 20th. Sadly, the $1,526 excludes any sort of wireless broadband connectivity, but small is still appealing in its own right, we suppose.
