Nexus 7 vs HTC Flyer
One 7 inch tablet that has the capabilities missing from the Nexus 7 is the HTC Flyer. The Flyer, announced in Fall 2010 and shipped in Spring 2011, has a slower processor and lower screen resolution than the Nexus 7. But it does have the following features:
-- HDMI output via MHL hardware (cost about $15)
-- Micro USB card slot
-- removable 4000 mAh battery
-- front and back cameras
-- digitizer for stylus input
Other Flyer specs include
-- 7" color LCD screen, 1024x600 pixels
-- 1.5GHz Qualcomm single core ARM processor
-- 1GB RAM
-- 16GB or 32GB Internal flash Storage
-- 5 Megapixel Camera rear camera
-- 1.3 Megapixel Front-facing Camera
-- GPS chip
-- Bluetooth and WiFi b/g/n
Used or Refurbished Flyers show up from time to time for less than $200. Here's a used one I found today for $159 with free shipping

The Flyer originally shipped with Android 2.3. An update to Android 3.x was released in December 2011. No schedule for update to Android 4.x has been announced.
The Flyer is thicker and substantially heavier than the Nexus 7, making it less comfortable to hold in one hand. Not a problem if you're planning to mount it in your truck!
Most Flyers were sold as WiFi only models. A couple of USA cell phone carriers sold the Flyer with a 3G modem. US Cellular and T-Mobile sold the Flyer, and Sprint renamed it the EVO View 4G.
My guess is that HTC will announce a Flyer 2 model later this year, with updates to the processor and screen resolution. But it won't cost $200, more likely $300.
