OVERALL: this is a new technology, not a tablet PC. As such it does not rely
on a hard drive or have the associated potential altitude related problems
or fragility. It is easily readable in incandescent light, and gets better
in outdoor light (no washout like an LCD). Requires external lighting at
night (not self illuminating). Extremely long battery life (up to three
days)

EFlyBook sounds cool. Especially the battery life. That's amazing!

I have a similar approach, but not as refined as I end up having to
manage all the SW and plate downloads to the tablet.

I have been using the Fujitsu ST4121 tablet PC in my Cherokee for
several years. The benefits: With one device, I get:
-Moving map GPS
-WxWorx Nexrad
-MP3 player
-Approach plates (via pdf)
plus a fully functioning Wifi enabled PC

The choice of tablet PC is critical. As you pointed out most
laptop/tablet displays are not made for outdoor viewing. It has to be
a transflective display, or the screen will be washed out on a bright
day.

So far, no HDD issues for me, even though I regularly fly at 10-11k
feet. I suspect the newer generations of hard drives are much less
susceptible to density altitude problems.

Problem with the upcoming Sony is that their receptiveness to other people's
software is limited, so it is unlikely that Myairplanes.com will ever be
seen on a Sony machine. Their big advantage is their compression algorithm-
otherwise all of their included info would be many gig.

If 10K-11K is about as high as you ever get, I would not expect you to
notice any sigificant loss of lifetime for the hard drive. They are
typically rated to at least 10K feet, meaning they are specifically designed
to operate normally up to that altitude.

It's the people who fly much higher than that (without pressurization, of
course) who are likely to run into problems. I doubt it's a generational
thing. I think it's just that you're not doing anything that would cause
the drive to fail early.

That said, I do think that solid state, non-volatile storage, electronic
paper such as found in the eFlybook is the future. Personally, I'm hoping
for electronic paper configured as sheets with holes for a binder and some
sort of easy-to-use PC interface (maybe wireless, like Bluetooth, so you
don't even have to plug each page in individually), so that you can prepare
a binder of all the charts likely to be used (according to plan and backup
plan) and be assured they are imaged correctly before the flight starts.
The eFlybook is a good step forward, but it still has the problem that if it
fails in flight for some reason, you can't switch to the next page you need
for the flight.
