I have been using an Asus A696 with GCzII since last february. GCzII has worked very well, providing me with all the information I need: it displays all of the Cache info that appears in the PQ, static Google maps, attributes, logs. It can handle field notes, although I have not used this feature. Caches can be downloaded from geocaching.com or can be loaded from PQs or GSAK exported GPX. The Asus has bluetooth and wireless so it is pretty convenient. I am not very happy with the GPSr (too imprecise) in this unit so I back it up with a Triton 500.
