HP Plans The Uber-Calculator

Compenguin writes "Over at TiCalc.Org information has leaked out about the new HP Xpander. Reported specs: 133MHz RISC processor (downclocked to 66 for power consumption), 320x200 screen 256 shades of gray, MP3 playing capabilities, and a "futuristic look." There is also a rumour flying around that it might run Pocket Linux as its OS. " Check out HP's page as well - and see our prior post on the 49G, the parent to this model.

    Running a fast CPU takes quite a bit of energy, and nobody is going to want a calculator that uses up four AAA batteries in 4 hours.

    Another reason is that those old CPUs are quite cheap AND small. Put a 68060 (32bit, much faster) instead of a 68000 in a TI-89 and it'll probably cost a bit more than $140.

    Of course, those old calculators probably weren't running 0.18 micron versions of those old CPUs; if they were, they'd probably be running at 66MHz as well.

    2. Software

    I am probably among a select few people in that I know almost all of the HP48's fuctions (and used them for usefull purposes in my engineering classes). The HPs software is easly worth the cost of the calculator, now with the 49G and more symbolic stuff this is even more true. Would you want to load your MathCAD, Maple and Mathlab on you palm.

    Why do I want this? I see this as being an all purpose data collector and field analysis tool. For me to do some field work requires both a calculator and a laptop. A PDA optimised for engineering use would kill two birds with one stone. Right know I thinking I could port or program specialized engineer software to it and be able to design revisions quickly and accurately in the field. Another use for this device is a data collector (ala survey total stations and GPS) the HP48GX is still a industry standard in this deparment but is getting too old and slow to be used in new inovations, like real time GIS data while you survey.

As a concession to the infix (1 + 2) TI crowd, in the last hp calc (the 49g) RPN could be buried in a way so that you didn't have to see it if you didn't want to. But the calc was still RPN (1 2 +) underneath, or else the core hp fans would have gone nuts. Many people have reservations about RPN because they learned infix notation first. RPN is fast and natural, but switching is weird. But pretty much everyone who uses RPN had to switch from infix notation, and it's not very hard. Knowing RPN can also come in handy when learning new computer languages (like postscript).

      HP decided early on that "RPN-vs-infix" debates are difficult to win, so the HP's since the 28s (maybe earlier) have included full algebraic (infix) notation support. You can always type
      '1+(2+4*SIN(3.14))^2'

    I find the TI-82's keyboard layout awkward and clunky compared to the flexibility that one might be able to build into a palm app. (OR! a springboard module, hint hint handspring!) For those familiar with the keypad layout, I'm sure a palm app could be devised which emulated the same on-screen.

    Especially when programming. I've often wished for a QWERTY keypad layout on the calc. I can tap out the function names much faster than I can pull them up using the TI-82's menu system.

    Are you going to sit in math class trying to tap your way through a tough calculus problem? I think not.

    Given the possibilities of interface customization, the built in IR port (no TI-Link cable required!), the superior graphics and speed (again, TI-82 experience only)... I'd much prefer that route over the HP Calc. All it would really take is some planning, and good, intuitive interface design.
