But it might be an option for people with different personal preferences. After trying every possible combination of settings, for me they all either scaled Adobe too much or everything else too little, or both, and I ended up undoing all of this and simply turning the resolution down one notch. Be aware, however, that this makes everything, including the appearance of your artwork, slightly grainy as if it was a pixel image that had been scaled up, and that the same Windows scaling applies to Adobe stuff as everything else including web browser etc. It allows you to make AI and PS auto-scale with everything else according to your Control Panel\Appearance and Personalization\Display settings. See this question regarding possible risks. Warning: it involves hacking the registry, to enable 'external manifests'.
If you're on CS6 on Windows, there's a hack described here which works on Windows 7 and 8.
Sadly that option doesn't exist in pre-CC and it sounds like Adobe have no plans to fix this. John Manly's answer works for Adobe CC as of the 2014 update.
