Maximum PC: "Over the last couple of years, many a company has entered the tablet market with high hopes, found the going tough and become an also-ran. Kupa may not be the most recognizable of names in the tablet world yet, but it is trying its level best to avoid that fate. Having entered the market with the Windows 7-based X11 Pro Tablet earlier this year, the Santa Monica-based company is now trying to stand out with the UltraNote, a modular tablet that runs Windows 8."
I'm digging the user-replaceable battery.
Kupa? Haven't heard of them.
