That means it also has the limitations of Steam: SteamOS is not the replacement for Windows 8 you've been waiting for. Beyond basics like browsing the web, there's little in the way of standard OS functions. While Valve reps showed off slides of the box's vanity shots using a Windows PC, I asked how I'd view such shots from within SteamOS -- the answer is that there's no real way to do so, as there's no file browsing system or image viewing application. While these limitations may not affect the vast majority of Steam Machine buyers (who are essentially buying a game console), it certainly impacts folks who are looking at Steam Machines as a replacement for their standard PC. Make no mistake: Steam Machines are PCs posing as game consoles, which comes with both positives and negatives.
