Until now, all of Verizon's 4G has been packed inside dongles. Samsung and Novatel's LTE hotspots will let you spread the 4G around with Wi-Fi. Slightly thicker than the old MiFi, but you need the space for all them Gees.
No price or date—or battery life spec—for Samsung's 4G Hotspot or Novatel's MiFi 4510L yet, unfortunately. Just that they'll support up to 5 devices.
Samsung's also got a new LTE version of Galaxy Tab as well. It's prettier, but basically the same inside (even still running Android 2.2) and they're not talking price difference (if any).
