I hope, I can get it running fast!  AVNET-MEMEC told me I can  speed  up
my design be using there Reference Designs and schematics.

It is a little bit picky to get the Marvel on a  SO-Dimm  together  with
512 MByte of Memory and a NAND Flash but it can be done.

However, I have send him the photo of the SO-Dimm JPG you send me and he
told me, that using two big 256 MByte DDR2/3 will be expensive.

It is complete (but no webcam) and only the SO-Dimm is missing 
But I am not sure, whether it has an Ethernet plug

I have bougt an 8" TouchScreen with 800x600 from Formike and I was realy
surprised when I had the TFT in my hands...  the TFT  Display  has  more
weight as the PCB and the LiPoly together.

The PCB is a little bitbigger then the 8"  TFT  because  it  is  mounted
diectly and on the backside I have a

1)  Formike     65 US$  8" TFT Display KWH080KQ03-F01
2)  SouthRiver  10 US$  LiPoly 3.7V/6Ah (100x125x5mm, ~130g)
3)  TI           7 US$  PMIC with charger
4)  TI          26 US$  Sitara AM3517
5)  Infineon    38 US$  2 x 128 MByte DDR2 (quit expensive)
6)  Micron      22 US$  GByte NAND Flash (comp. 4 GByte version av.)
7)  microSDHC    5 US$  2 x up to 32 GByte
8)  TI           3 US$  ADS7846 TouchScreen Controller
9)  Maxim        5 US$  MAX2769 GPS (wrks with SPI -> NMEA)
10) National    21 US$  LMX9838 BlueTooth

In total 202 US$ + Shiping, VAT, Bank fees and watelese.  PCB  prototype
was arround 1300 Euro (Made-In-Germany :-) do to its size.

In Mass-Production with 10.000 pcs, the 10 main-parts would  cost  under
60 US$...  and the PCB arround 5 Euro.  This is only an overview and all
prices are for Sample-Quantities

But now I have to redesign this pig, because I have a space problem with
Wifi and GSM/UMTS/HSPA.

OK, this is my base config andI like to do it for the  TI OMAP 3530  and
Kirkwood 88F6281.

The battery can be changed to a 12Ah type by doubling the  thickness  to
11,5mm which should be acceptable.

This mean, in total, the TablePC is arround 230x160mm with  a  thickness
of 20-25mm and a weight of 600-1000g depending on the used plastik/GFK.
