Obviously, this does not forget the controversy that Lenovo got themselves into, but it is certainly the correct response (if they act how they imply). Adware and bloatware is common to find on consumer PCs, which makes the slowest of devices even more sluggish as demos and sometimes straight-up advertisements claim their share of your resources. This does not even begin to discuss the security issues that some of these hitchhikers drag in. Again, I refer you to the aforementioned controversy.
In response, albeit a delayed one, Lenovo has announced that, by the launch of Windows 10, they will only pre-install the OS and “related software”. Lenovo classifies this related software as drivers, security software, Lenovo applications, and applications for “unique hardware” (ex: software for an embedded 3D camera).
It looks to be a great step, but I need to call out “security software”. Windows 10 should ship with Microsoft's security applications in many regions, which really questions why a laptop provider would include an alternative. If the problem is that people expect McAfee or Symantec, then advertise pre-loaded Microsoft anti-malware and keep it clean. Otherwise, it feels like keeping a single finger in the adware take-a-penny dish.
At least it is not as bad as trying to install McAfee every time you update Flash Player. I consider Adobe's tactic the greater of two evils on that one. I mean, unless Adobe just thinks that Flash Player is so insecure that you would be crazy to install it without a metaphorical guard watching over your shoulder.
And then of course we reach the divide between “saying” and “doing”. We will need to see Lenovo's actual Windows 10 devices to find out if they kept their word, and followed its implications to a tee.
