The tablet landscape has changed greatly in a year's time, at least if you gauge what we've seen on the CES show floor. The 2012 expo was led mostly by high-end Android tablets. This year, Windows 8 understandably garnered much more of the spotlight now that it's available, while Google's platform mostly surfaced in the budget category, where it was much more prevalent than before. Whatever the platform, we saw our fair share of experimentation -- some companies weren't happy with just a spec bump in a familiar form factor. Check past the break for some of the more daring (or at least well-executed) examples from CES 2013.
