The makers of Rhino have just release a new iPad & iPhone application to allow you to look at your models on your coveted portable apple devices.
There is nothing like showing your designs and ideas in 3-D. Pan, zoom, and rotate with a tap or drag of your finger. The handy navigator lets you scroll through thumbnails, so you can quickly jump to any model you want. Load Rhino models from web sites, Google Docs, email attachments (iPad only), or from iTunes (iPad only). Save views as images for markup and emailing.
Available in the 
store for only $3.99, could be worth checking out if you show your Rhino models to users.
via iRhino 3D – View native Rhino 3DM files on your iPad, iPhone, and iPod touch.
