Just received the P-5000 today, and it's a MAJOR UPGRADE with VERY
significant improvement on what was already the king of
storage/display/Card-backup units.

The big changes?

Here are the significant changes I've noticed so far...

-WAAAAY faster!! -500% faster viewing of files (rendering), and
nearly-instant thumbnail appearance, which was a pain on the previous units
-Better, more straight-forward menu system for basic operations
-Much faster copyying (more than 200% faster)
-Larger (4") screen, which now displays 24 bit color (!).
-You can now ZOOM in on RAW files...AND...they display JUST AS QUICKLY as
their jpeg counterparts!  How did they do that???
-Excellent "delete mode" for quickly eliminating junk-files
-Capability to hook up DIRECTLY to an external hard drive for
back-up/redundancy (very useful) via full-size USB connector on unit
-HUGELY improved video file handling (now handles .avi, .mov, .div, .divx,
.mp4, .mpg, mpe, .asf, wmv, .m4v, mod, vob...just about anything you're
likely to use)
-Memory cards are no longer inserted in an "upside-down" manner
-Blown highlight and shadow indicators when you desire
-Zooming tool!  -You can select the portion of the frame you want to check
focus on, and zoom DIRECTLY to that portion at 100%. --Very helpful, and
saves fiddling.
-Adobe RGB display support!
-Computer-upload software for easy back-up/up-load to PC
-Easy * rating system for tagging images, and then sorting according to
rating--very cool
-Control over how thumbs are displayed, including size of thumbs,
information shown, and even a small 64-image-per-page mode! -Which works
amazingly well due to the large, high-res, 24 bit screen
-If you like using it as a slide-show viewer (which also feeds a TV or
projector), the transition effects are extremely smooth and classy
-You can even connect a USB flash drive directly to the unit for file
transfer/viewing
-AND...you can use the full-size USB port to connect to STANDARD CARD
READERS...which opens the unit to back-up of ANYONE'S images from ANY
source.
---The above also means that you can "hand off" images to someone's USB
device...without a computer. Very cool abilty.
-Full file management, with folder naming and file naming FROM WITHIN THE
DEVICE
-Music fans will appreciate the addition of WMA and M4p files, instead of
only mp3.
-Music fans will also appreciate the inclusion of a file converter if you
don't use the above formats
-More for music...You can now shuffle and repeat lists of tunes

As I noted above...this is a MAJOR UPGRADE which answers every single gripe
I've ever had or heard with regard to Epson's great-but-imperfect
P-2000/P-4000 units.

I honestly can't think of anything they left out...and they thought of some
very useful features I hadn't even thought to wish for.

Very pleased.
