Tim wants a viewer for his Android phone that allows him to view SolidWorks 3D models. He uses one but it keeps crashing. He's moving to the iPad. Leo says it may be a memory issue, not a processor power issue. The crashing is happening when the model is too big for the model to load.
Another option is to get a Windows Surface Pro 3. It'll have more memory and runs 64 bit, but it's not cheap. A high end tablet will do it, like the Samsung Galaxy Tab Pro. The Samsung Galaxy Note Tab is an option, but the screen isn't as good. But the 12" has 3GB of RAM, as does the Samsung Galaxy Tab S. The Lenovo Yoga is very good too, but it's only 32 bit. There's also the new Google Nexus 9 to consider.
