It seems that no other application can move Steam from the first place
Canonical has published a list with the most downloaded free applications on Ubuntu Software Center, for June.Splashtop Streamer, a high-performance audio-video streaming server, enabling remote access from an Android device (tablet/phone) or an iOS device (iPad/iPhone/iPod), is in the tenth place.
Nitro, a task management software that will help people organize their days in a more efficient manner, which comes with Dropbox and Ubuntu One support, is in the ninth place.
IntelliJ IDEA 12 Community Edition has gone up a few places and landed on eight. This is a free and open source version of IntelliJ IDEA, a well-known IDE for Java, Groovy, Scala and Android.
CrossOver is in the seventh place. This is an application which allows users to install many popular Windows applications on your Linux computer.
ScreenCloud is in the sixth position. It’s an easy-to-use screenshot tool that can be used in a large number of instances.
Plex Media Server, an application that makes it possible for users to stream music, (local and online) videos and photos from the Ubuntu desktop to the TV, Roku box, Android phone, iPhone, PlayStation 3, and Xbox360, is now in the fifth place.
YouTube to MP3, an easy-to-use software which can be used to download YouTube videos as MP3, has remained in the fourth position.
Master PDF Editor, an application used to view, print and edit PDF and XPS files, is in the third place.
Motorbike is still in the second place. This is just a casual bike skills game, full of action and real physics dynamics. Be careful though, it only offers the first 10 levels for free.
Steam, the client for Valve’s digital distribution platform, is still the most downloaded application on Ubuntu Software Center and it will probably remain in this position for a lot time.
