Corporation Google officially announced that today the operating system Android, version 2.2 is not optimized for use with tablet computers. It is for this reason that many questions arise when it is used in this way.
The world has already presented several models of "tablets" that are running this OS. The most striking example is the Samsung Galaxy Tab, which is more of a large smartphone than a full-fledged tablet computer. There are other representatives, fakes have already appeared, like Chinese iPad (aka aPad).
And everything would be fine, but many applications that run perfectly on smartphones refuse to work correctly on tablets. The reason is that they were developed for other platforms.
But the situation is not at all sad. Google immediately told that the new version of the OS - Android 3.0 (codenamed Gingerbread), is being developed with these nuances in mind. So there is a possibility that iOS a worthy competitor will appear in the near future.
But as regards webOS and tablet from HP, so far everything is deaf.
