Face to face in the news:

2012 - SharePoint 2013 will include SkyDrive Pro

Together with Office 2013 Microsoft unveiled the beta version of SharePoint 2013. This is still an early version, and we won't review it so far (in particular, it's still no information about possible integration with Yammer). But one thing is this beta has already attracted great public interest - SkyDrive Pro. We have previously reported that SharePoint is being attacked by the army of file synchronization services called "Dropbox for Enterprise", and that SkyDrive's technology should help SharePoint to overcome these attacks. And so it happens, but as usual, Microsoft has added an element of chaos to this project. Why was it necessary to create a separate service called SkyDrive Pro? Why they just not added simple file sync functionality to SharePoint without inventing new titles? It's even more confusing as SkyDrive Pro won't replace the existing off-line client - SharePoint Workspace, but will be used along with it.

SkyDrive Pro also won't be connected with a conventional SkyDrive, and users will be using both services separately (eg, one for work, one for personal use).

SkyDrive Pro will be shipped with SharePoint Online in Office 365, as well as with the local version of SharePoint 2013. The second option will allow companies to create own SkyDrives behind the corporate firewall.

2012 - SkyDrive comes to Windows, MacOS and iPad. Reduces free storage to compete with SharePoint

SkyDrive, Microsoft’s online storage service continues to take on Dropbox and add support for new platforms. Following the applications for Windows Phone and iPhone, Microsoft has released the desktop client for Windows and Mac OS (OS X Lion). Also, the SkyDrive's mobile interface has been optimized for iPad tablets. SkyDrive for desktop works in the usual way - it creates a folder on your computer and all the files that you copy to this folder are automatically synced with your online account, as well as with your other computers or mobile devices that are running SkyDrive. And if in the online account you create a shared folder for your work-group, the service will be continuously syncing files between the computers of co-workers.

In addition, SkyDrive for Windows has an option that allows you to remotely access any file on your computer (not only those files that are located in the SkyDrive folder). For example, you can use your smartphone to access your office computer and find the needed document or watch the video from your computer remotely (SkyDrive supports file broadcasting). Of course, all this is possible only if your remote computer is online.

The bad news is that SkyDrive reduces the limit of free disk space from 25 GB to 7 GB (for new users). Existing users who have used less than 4 GB will be also downgraded. But if you right now visit this page and click the button, your free 25 GB storage will be saved.

2000 - Microsoft Web Parts make it easy to create internal portals. Beware OneDrive

Microsoft Web Parts
Microsoft has introduced a new technology Web Parts for SharePoint Team Services. SharePoint Team Services - is a new name for Office Server Extensions - the web extensions for Windows Server that allow companies to create internal websites aggregating data from internal and external sources and view them in Outlook. New Technology Web Parts will greatly facilitate the creation of such sites. Web Part - is a Web page block that can be reused in multiple sites. This makes it possible to use already existing blocks, created by Microsoft or other companies (for example, a CRM developer can create a web part for its CRM system and the customers will only have to insert it into a web page). Portal users can choose the parts they need and arrange them on a web page. The data exchange between the web part and third-party applications and data sources is XML-based .
