Opera launched Opera Mini 5 beta for Windows Mobile 5- and 6-based handsets. While Opera Mini traditionally requires Java, the new Windows Mobile version does not, which means that Opera Mini will work on any Windows Mobile phone. Opera Mini 5 beta for Windows Mobile includes the same rich feature set as the Java-based version. Renowned features, including tabbed browsing, the password manager, bookmarks and Speed Dial, are built-in to deliver convenience while on-the-go. One of Opera Mini's major benefits is that it compresses data traffic by up to 90%, resulting in significantly improved page-loading and speed. This results in a dramatically reduced data load, which can translate to lower browsing costs when on a pay-per-MB data plan or when on expensive roaming.
