Samsung adds yet an other tablet to the Galaxy series at Mobile World Congress 2012-- the Galaxy Note 10.1, an upsizing of the Galaxy Note phablet with Wacom S-Pen support.
Looking very similar to the Galaxy Tab, the Note 10.1 runs on Android 4.0 and carries a 10.1" WXGA display, 1.4GHz dual-core CPU, 1GB of RAM and up to 64GB of internal storage (expandable via microSD slot). It also has x2 cameras (3MP back, 2MP front) and connectivity via HSPA+ 21Mbps radio, wifi and Bluetooth.
More interesting is the S-Pen support-- with a number of optimised apps such as an updated S Note note-taking app, with new shape- and formula-matching functions. The tablet also includes pre-installed versions of Adobe Photoshop Touch and Ideas, complete with pressure sensitivity support.
Samsung also plans to release the S-Pen SDK, which should boost developer support somewhat.
