Title: NEC MobilePro 780 and 790

MSRP $899

Summary: (Full Review) TechRevu contributor and former editor Daniel Dern likes the size, portability, long battery life, and instant-on capability of NEC's "Jupiter Class" sub-notebooks.

Though not as full featured as a laptop, he finds them better for instant writing gratification, and knows he's not alone from the other journalists he sees.

Though he finds devices like this extremely useful he laments the lack of drivers for peripherals for them making networking and device sharing less than perfect.

  Full Review:  NEC MobilePro 780 and 790

For many people I know whose out-of-office computer use includes lots of typing,
NEC's MobilePro 790 handheld computer), and its predecessor, the 780, has proven ideal.

I've been using a 780 for over two years now, as have fellow technology journalists
(among their many hats) Jerry Pournelle, David Em, and John Ruley.

In particular, I use my 780 for walking around trade show floors with -- pop open, grab a quote or other info, pop closed and move on, attending events, writing up notes and articles on planes, trains and in waiting rooms, noodling on things at home when my desktop PC is off,etc. I've used it to write thousands of words, read and edit (some) documents, and do some digital picture looking-over, plus a little bit of web browsing and email; I believe that John Ruley's also given some of his Power Point presentations with his.

There are smaller devices with keyboards, e.g., HP's Jornada 728, the ultimate result of a long lineage that started with the HP95LX, a Dos based clamshell that many feel has never been bettered, certainly not by Windows CE devices, but for writing, I like NEC's form factor.

TechRevu's Editor (Ernest Lilley) and others seem able to pound out thousands of words on the little Psion handhelds (some using the two-thumb method), and some people even crank kilowords out on the still tiny chicklet-keyboard HP 620's. But if these are too small for your fingers, then you want to check out an NEC MobilePro 790 or 780.

The MobilePro 790 belongs to the "Jupiter" class of "handheld PC" Windows CE machines, whose features include:

  • Good close-to-full-sized keyboard
  • "Instant-on"
  • Built-in software in ROM: Windows CE (now called Windwos for Handheld PC), includes WinCE versions of MS Word, Excel, PowerPoint (viewer only), and Pocket Internet Explorer, plus TCP/IP stack and PDA-type apps
  • Lithium-Ion battery good for full work day
  • 1 each Type II PC Card and CompactFlash slot, e.g. for Ethernet, 802.11, MicroDrive or
    solid-state storage.
  • V.90 modem.
  • Weight between 2 - 3 pounds.

The 790 includes 32MB RAM, half of which is available for storage;
half-VGA (620x240) 8.1" diagonal DSTN color touchscreen; and serial/VGA/IR/parallel and audio ports. (No USB.) The battery's good for
6-8 hours... and there's a 6-cell AA battery shell available, for "recharging
in a drug store."

As a comparatively low-powered device running WinCE rather than a full Windows,
the 790 and its brethren aren't meant to replace a notebook or desktop computer --
but if you're looking for extreme portability, battery life and convenience, you should be considering one of these puppies. The keyboard is excellent; the international power supply is about the size of a deck of cards folded in half; the whole set-up weighs barely two pounds and goes painlessly into any sidebag -- and, because of the half-height size, if I'm using it on a plane, when the person in front me of slams their seat back, they won't hit the screen and smash it..

"Instant-on" is a large part of this machine's value for me. Press the power button
even with a file open and it goes dark instantly -- before your finger finishes
pulling away; press it again (or open the machine) and the 790 "wakes up" near-instantly (maybe a second). In my experience, Windows notebook "sleep" and "hibernate" modes can't even come close to this...

You should be able to do the usual PC/handheld type of synchronization activities;
however, I haven't tried any of this yet. (I don't use those apps.) I also haven't tried the infra-red ports, the microphone, or the audio.

Because these are zero-spindle (no disk drive) machines, you'll want some storage, e.g. solid-state CF, or (with adapters) SmartMedia, memory stick, etc., which keeps getting cheaper (CF and SmartMedia are currently running well under $100 for 256MB), or  Microdrives or PC card hard drives (up to 5Gb last I looked). There's also third-party floppy/superfloppy drives from Accurite.Com (and maybe Addonics) ... not clear if there's any CD readers or writers that will work with WinCE, though.

This brings up the main limit/frustration with all Windows CE devices -- limited availability of drivers, and other problems getting software.

Many devices, including PC Card/CF based or interfaced ones, simply don't support Windows CE. Many require you connect the 790 to a "host" Windows PC in order to extract and download said drivers or software.

Even more frustratingly, for many which allegedly do support, their vendors don't
seem to have made them available -- and tech support often has no idea what you're talking about. To add to the problem, these Jupiter-class machines are based on three or four different chip types (MIPS, StrongArm, etc.) -- and each needs its own version of a given driver.

Fortunately, this isn't a problem for storage... but pay attention when getting
EtherNet, Wireless and other cards, and external devices.

The MobilePro 790 lists for $899. I'm not sure it's worth that much. 780's and
790's can be found readily on eBay in the $250-$500 range -- but shop carefully, some units won't work perfectly. Better to pay somewhat more for a new-in-box unit, if possible. If you don't care about a Citrix client, a 780 will do you fine, and be
less expensive.

FYI, I have two other Jupiter-class machines -- IBMs WorkPad Z50 (discontinued) and HP's Jornada 820 (ditto, I think), and have been using them, particularly the HP, for several years. Of the trio, I like the NEC best, for form factor and portability;
although if I expect to be doing e-mail, e.g. at home, I'll use the HP 820 or the
IBM Z50, which have a 640x480 screens. But the 780's always just right for tossing
in my bag "just in case I have some time to write."
