HP Prime wireless kit

Quote:That's because you only have few, small files :)
USB on the Prime is annoyingly slow with several hundreds of KBs, let alone dozens of MBs. The protocol on top of HID is missing the "directory list" commands supported by most of the TI-Z80, TI-68k and TI-Nspire series: the dirlist command triggers a mere enumeration of the calculator's contents, instead of a lengthy, all-or-nothing backup.

That is correct. When I first got my Prime, I thought "gee, a picture on the screen would be nice" and searched for a way to add a jpg (TI nspire does that), but nada. Then I looked on the 'net and found a 'method' that tricks a graphics display GROB file into holding an image. Huge files! Slow speed! (and no compression as GROB is a bitmap)

But is that because of the volume of information or the (unexpected) size of a type of file or the little calculator brain just doesn't want to become an iPod?

For my purposes, being able to work with numbers and complex formulae on a portable, very low-cost device is more than enough. On my iPhone, I have (and use) a 12c, a 41c, a 42s and a 48GX and they all do more than their progenitors in the realm of speed. What they lack is a brilliant interface to the display capabilities of the host device.

I don't want to sound like a newbie-fan-boy, but the HP Prime nails the use of the tiny graphic interface for 'graphing' and working with data in stacks. The ability to manipulate data is amazing and the user interface is intuitive after some practice ("oh, now I see why they did that").

Nothing wrong with pushing the envelope on the capabilities of a device (BTDT, too), but one must be careful to separate the "test-pilot data" from the implications for the device in the manner it is intended to be used.
