But did Microsoft come through with a stable computing platform, with decent hardware requirements and a hardened security model? The definite answer is yes. I’ve been running Windows 7 on my laptop for over a month, installed all the applications I’d normally use – iTunes, Office, Firefox, Mozy – and they all worked fine, without any compatibility settings or whatnot.

While my computer is far from being state of the art, it is able to run Firefox, iTunes, Word and Photoshop at the same time, with decent speed. On just 1GB of DDR2 RAM and a 2,2Ghz AMD Turion 62 single core processor. The visual effects are fluid on a two year old ATi X200M graphics chipset with just 64MB of RAM. What they did under the hood, optimizing the code to run faster, is simply amazing. Running Vista on this laptop was like swimming with cement boots, even with the visual effects turned off.

A very important aspect for Windows users, security, has also been addressed in many ways, and while most of the technologies were present in Vista, they have been improved in Windows 7. The UAC (User Access Control) dialogs are less frequent and not so annoying, executables are scanned for digital signatures of their vendor, you are notified about files downloaded from the internet as well as an improved firewall and notification center. DEP (Data Execution Prevention) is enabled by default, we still have the KPP (Kernel Patch Protection) and a significantly improved Autorun. Also, the privilege level of your account is not root, which would grant you unlimited access to system resources, but a member of the Administrators group. To affect changes that may affect system integrity and security you have to accept an UAC prompt. In addition to this, all start-up items that access critical system areas are also required to be manually approved via an UAC prompt. Checks and flags are implemented all around, to the point that you would have to ignore multiple security warnings in order to get infected. These are all significant changes from Windows XP. All around, you can see that the engineers have dedicated a significant amount of time to securing the operating system.

From such an important aspect as security,we go on to examine the improvements in the user interface department. The taskbar, part Mac OS X dock, part Start menu is an elegant and comprehensive UI element. The functionality offered is simply amazing; We have quick access to commonly used applications, an amazing way to find the window you’re looking for with Quick Look, a streamlined notification area which is clean yet retains usability and instant search from the Start menu. I’m sorry to disappoint the Linux and Mac OS fans, but Windows 7, as it is today, has the most advanced and usable UI.

With Windows 7 Microsoft has changed the game. I for one was saving money for a MacBook, which from a Windows XP viewpoint is an incredible upgrade. But compared to Windows 7, not so much. We have performance, stability, a not too shabby security model, an incredible selection of hardware and software. If lastly, we consider the price – free until June next year – we have an incredibly attractive offer. The ball is at Apple and the pitch is going down at WWDC. Unless something amazing comes out, it’s going to be a homerun for Windows 7.

As always, I’d love to hear what you think about this topic. You can check out How To Install Windows 7 on a Virtual Machine with VirtualBox and Test Windows 7 RC on a Virtual Machine written by Guy McDowell.

Founded in early 2007, Wixi has continually added more functionality, and at this point is an quite amazing service. While being more Gamma than Beta, Wixi appears to be a feature complete service – allowing you to easily upload, manage, view and share media. I didn’t encounter any issues while using the service – no errors or freezes – and enjoyed reasonable fast uploads (200-300KB/s). I didn’t expect that a service using a mix of JavaScript and Flash will behave so consistent and snappy.

Wixi’s interface – clearly designed to appeal even the least computer-savvy users – resembles your desktop – windows, menus and, of course, a wallpaper of your choosing.

One of Wixi’s strong points is the ability to set access levels to files; private, friends or public. You wouldn’t want to share your final essay with the whole world, would you? Because you can pick individual people with which you want  to share a file or a folder, you can work together with your friends on a project, and not worry about sending each revision over email to the other participants.

Once you invited your friends to Wixi, you are automatically updated with their public activity via the Friends Activity Report. Arranged by media type, you could find pictures that your girlfriend took on the trip, or just as easily, the new school timetable posted by a colleague. Wixi has a lot of real-life uses that differentiate it from the other storage services – because of the tight integration with social aspects.

Social tools on the site allow users to interact with their friends online, across campus or across the globe, sharing a cool new song or photos of a recent vacation or family event. For those without access to their computers, Wixi offers long-distance access to media files. Registered members can also meet fellow users, browsing their Wixis, discovering new media and expanding their social circles.

Wixi also enables you to discover new content by simply browsing other people’s public ‘wixis’; if you find something you like, you can leave a message, save the file to your Wixi or request to be friends with that person.

Another interesting feature is ‘Web Channels’. Recently implemented, Web Channels lets you search, save and view content from YouTube, Daily Motion, Flickr, Hulu, CNN and MTV Music.

With offices in Paris, New York, Buenos Aires and half a million dollars in funding, Wixi has set a high goal for itself, ‘a world-class community for millions of users’. Their goal is far from unattainable if they continue adding features, maintaining the service reliable and easy to use. Wixi certainly gets my thumbs up, with the same concerns I have for any cloud storage service: privacy and data safety.

You can sign up for free at wixi.com; the free option gives you 3GB of storage and just a couple of restrictions, such as streaming files under 100MB. The premium option removes al the restrictions and gives you unlimited storage.

The first 50 readers who send an email leave a comment on the blog will get an code for the premium service; If you want to say thanks, include in your email a cool service, website or software you’ve discovered or a topic you’d like me to cover. This will help me pick future stories according to your interests.

As always, I love hearing what you think, in the comments. Have you previously used Wixi or a similar service? What could be improved?
