Best portable map to help when doing IFR flight

I went up with a friend who is a CFII to do some night IFR last
Tuesday. Everything went fine, except when So. Cal. cleared me to RAL
for CNO GPS-B while I was going out bound from the published hold at
PDZ, I could not get RAL programmed into my Trimble 2000 Approach as
the IAF. I tried it again, and it just sequenced to HINTIN by itself.
RAL VOR was out, so I could not pick it up on my NAV/COM. Finally, my
friend gave me a heading to RAL from his Anywhere Map. Everything went
fine after that.

I will study my Trimble 2000 Approach's operation to find out what I
did wrong. But my friend's Anywhere Map showed me the value of having
a color moving map during IFR approachs, and now I want a color moving
map for myself.

I know panel mount like Gramin 430/530 or 480 w/MX20 are nice, but I
have no budget for a panel mount right now. So, I am looking for the
best portable map FOR IFR FLIGHT on the market.

The following are a list of features that I wish for. But I am willing
to settle for something that is as close as possible:

Color,
Bigger the better (to help with my aging eyes),
Approach procedures (at less with final approach waypoints like Garmin
296, but all waypoints, including waypoints for ILS and DME, will be
nicer),
Holding patterns,
Terrain warning,
Vertical navigation for published LNAV/VNAV and LPV approaches (are
they available on any protable?),
Automatic log book.

I will consider PDA or PC based system as well.

Your suggestion?
