With that out of the way, let's talk hardware. Lower on the list of gear is the keyboard-laden Tidal with a 6-inch, 600 x 800 screen and 2GB internal storage. Just above that is the Tidal Touch with a 9-inch, 768 x 1024 screen, earphone / mic jack, 4GB internal upgradeable to microSD. And then we've got Ocean, which comes in 6-inch (600 x 800 pixels) and 9-inch (768 x 1024 pixels) variants and both feature capacitive touchscreens, 802.11b/g WiFi, tilt sensors, 4GB internal storage expandable via microSD, and some form of earphone / mic jack. Both Tidal Touch and Ocean 9 have optional 3G connectivity (that in the process halves internal storage to 2GB and nixing the microSD slot).
