Aha! So this is why the red Dell Streak has been so hard for some people to track down: the cherry casings are hanging out in China and being sold as part of cheap knock-off tablets that surprisingly seem to be packing some pretty decent specs.
The WELLDONE tablet PC/phone hybrid, as I guess it's called, combines a 1.2GHz Cortex A8 processor, 512MB memory, Android 2.3 Gingerbread, and 3000mAh removable battery with what appears to be a PDMI connector for charging (and docking?), a mini USB port with OTG host functionality, and HDMI out via an optional and unseen dock. It's all packaged in an 8.07" x 4.25" x 0.56" tablet that features a 7-inch WVGA resistive touchscreen, tips the scales at about 13 ounces, and can be used to make phone calls too.
Wait a minute, a 7-inch screen? So it would seem.
This, of course, means that the often MIA red Streaks were in fact not in China all this time, as the red bodies being used here are actually for Streak 7-alikes that only look like Streak 5s with rotated buttons that prioritize portrait use.
I think it's just a consistent typo, personally, as almost everything about this WELLDONE device looks exactly like a 5-inch Streak.
I guess the only way to find out for sure is to actually buy it; and at a shipped cost of only $216 (one tablet plus shipping through DHL), that may not be such a bad idea.[AliExpress] Thanks, curtis!
