The Palm Pixi Plus features 16GB of memory, webOS 1.4.5, and mobile hotspot functionality. It also features quad-band GSM and UMTS 850/1900 for compatibility with AT&T and its affiliates.
Readers we do caution that webOS 1.4.5 has known security issues that HP has stated they have no plans to fix. The device cannot be updated to webOS 2.0, even with unofficial firmware, at this time. While HP leadership did commit to updating the Palm Pixi Plus (and all other first-generation devices) to webOS 2.0, they later backtracked from that commitment, despite mistakenly updating the Palm Pre Plus later.
The Pixi Plus has a slower CPU than the Pre Plus, and due to that limitation (as well as no available firmware to hack from) there is no known way to update the device to webOS 2.0.
Due to the aforementioned security issues, we suggest this as a good GSM backup device, but not for daily use when connected to a network or Wi-Fi.
