The NZ90 is also the first CLIE to integrate Bluetooth like with Palm's Tungsten T. It also has a CF 1 slot to supports Sony's $150 WiFi 802.11b network card. The new CLIE, like the NX70V, also has a large 320 x 480 pivoting screen for tablet mode with virtual Graffiti and incorporates a voice recorder feature to record and playback voice memos. Another nice feature of the new handheld is a redesigned keyboard with square keys and a more familiar layout.
In addition, the NZ90 is only the second Palm OS PDA to include a removable lithium-ion rechargeable battery pack. Handera was the first. The "Smart LITHIUM" battery pack has its own circuitry to indicate the remaining battery life in minutes. Additional Battery Packs are sold separately for $ 79.99 each. The handhelds' new foldable USB cradle allows users to print images directly to a printer and it has an AV out plug to connect to a TV or monitor.
