\head{Overview}
\begin{slide}
TROG, ''The Return/Revenge Of the Geeks''

\blBul
  \item Based roughly on gta02-core
  \item Update subsystems
  \item Consider going 3G
  \item New case and LCM
  \item Kill Debug Board
\elBul
\end{slide}


\head{Update CPU}
\begin{slide}
E.g., Samsung 2450
\blBul
  \item 2D acceleration
  \item High-Speed USB
  \item 2$\times$SD/SDIO/MMC
  \item IROM
  \item Probably available in higher-capacity MCPs
\elBul
\end{slide}


\head{Maybe Update Modem}
\begin{slide}
\begin{tabular}{ll|lll|l}
   \bf Vendor/Model & \bf GSM & \bf Next & \bf Extra &
   \bf Size ($\hbox{mm}^3$) \\
   \hline
   TI Calypso	  & Tri  & --- & --- & $30\times 40\times 2 = 2400$ \\
   Telit GE865    & Quad & --- & --- & $22\times 22\times 3 = 1452$ \\
   Cinterion EES3 & Quad & EDGE & --- & $33.8\times 29.6\times 3.2 = 3211$ \\
   Telit UC865-E  & Quad & 3G  & --- & $36.2\times 30\times 4.8 = 5213$ \\
   Telit UC865-G  & Quad & 3G  & GPS & $45\times 30\times 4.8 = 6480$ \\
   Option GTM501  & Quad & 3G & HSUPA& $25\times 30\times 2.3 = 1725$ \\
\end{tabular}
``Size'' is above main PCB.
\end{slide}


\head{New Case}
\begin{slide}
\blBul
  \item Less ``Embedded Air''
  \item Flat bezel
  \item Features drive design, not the other way around
  \item E.g., room for 3.5 mm jack
\elBul
\end{slide}


\head{More Modest LCM}
\begin{slide}
\blBul
  \item Fewer pixels
    \blCir
      \item Less work when drawing
      \item Lower display refresh bandwidth
      \item No need to compete with laser printers (280 dpi)
    \elCir
  \item Perhaps larger size
\elBul

Note: sourcing LCMs seems to be hard.
\end{slide}


\head{Debug Board}
\begin{slide}
\blBul
  \item Eliminate fragile and anti-portable FPC, use IDBG
    \blCir
      \item Serial console useful for diagnostics
      \item Delegate control tasks to MCU (e.g., PMU, HDQ)
      \item Can be made a BOM option
    \elCir
  \item Add debug taps
    \blCir
      \item For experiments and tinkerers
      \item NC FPC connectors
      \item E.g., under LCM, where space is cheap
      \item Use standard 1:1 cable
    \elCir
\elBul
\end{slide}


\head{Miscellaneous}
\begin{slide}
\blBul
  \item GPS update: ublox5
  \item WLAN: Marvell 8686 or maybe radically different Atheros (or other)
  \item Optional camera
\elBul
\end{slide}
