I'm looking forward to seeing creative hacks based on this...

"... C# does strong type checking when you compile the generic type. For an unconstrained type parameter, like List, the only methods available on values of type T are those that are found on type Object, because those are the only methods we can generally guarantee will exist. So in C# generics, we guarantee that any operation you do on a type parameter will succeed."

Edit (more explicit quote):

"When you say K must implement IComparable, a couple of things happen. On any value of type K, you can now directly access the interface methods without a cast, because semantically in the program it's guaranteed that it will implement that interface. Whenever you try and create an instantiation of that type, the compiler will check that any type you give as the K argument implements IComparable, or else you get a compile time error."

Furthermore (related to the CLR avoiding boxing costs):

"I'm just pointing out that we do fairly aggressive code sharing where it makes sense, but we are also very conscious about not sharing where you want the performance. Typically with value types, you really do care that List is int. You don't want them to be boxed as Objects. Boxing value types is one way we could share, but boy it would be an expensive way."

The rendering engine (Gecko). I guess for it to make sense you must separate the drawing engine from the browser, which adds things like tabs, bookmarks, themes and add-ons.

OneGet can install applications from repositories, using any number of providers. The preview version comes with a version of Chocolatey [2] built in managed code (C#) instead of PowerShell, but it supports the same Chocolatey gallery (a repository of software packages) and protocol.

PowerShellGet [3] can install PowerShell modules (e.g. make new Cmdlets available on the PowerShell command line). The modules can be delivered as scripts or as compiled .NET assemblies. By default PowerShellGet is configured to use a (closed preview) repository [4], which makes it not very usable, but it's interesting to know what direction it is headed.

As a more practical alternative to PowerShellGet, have a look at PSGet [4], a PowerShell module for installing PowerShell modules, with its own dedicated repository. Hopefully Microsoft's PowerShellGet will support PSGet as a provider in the future as well, the names are certainly confusing.

Desired State Configuration (DSC) [6] is a new (Windows 8.1) capability to configure Windows using a declarative syntax extension of PowerShell v4. It can set registry keys, create files and directories, enable Windows Features, and more. DSC 'resources' are PowerShell modules, so DSC's capabilities can be extended, see this GitHub repository [5] for examples.

Alternatively, have a look at Boxstarter [7]. It can do installation and configuration, and you can host your 'starter script' online and launch it with a single command. Boxstarter will take care of all Windows restarts that might be necessary along the way.

Be aware that, although most modern package solutions for Windows are using NuGet as a packaging format, using NuGet.exe directly (the application) and with nuget.org (the website) is meant for managing software development dependencies, not installing/updating end-user applications or command-line utilities.

This type of experience (case) can then be carried forward to new projects, possibly convincing designers and clients. Although it might turn out they work just fine, it probably depends on the audience.

[1] Use Google Analytics events to track interactions (next, previous, pause, resume etc.), and add 'campaign' parameters to links inside carousels to compare traffic to product pages originating from carousel links vs. regular menu links (if any).

Can you explain this? Thanks!
