Why this is hard…


The technical challenges:


Battery Life


Memory Management (esp. on
iOS
)


.NET on ARM (Windows 8)


Thread Management (esp. in Android)


Consumer focus


Strong differences in platform
-
specific languages


Laptop vs. Tablet


Gartner
recommendations:


“Over analysis is a risk in an immature market.”


Rule
of Three: “If an organization is targeting three or more device platforms, if they
have three or more applications, or if they have three or more back
-
end systems, then
the multichannel or cross
-
platform tools typically yield better project results during the
course of three to five years than native tools.”


“Enterprises need to consider whether they can mitigate platform uncertainty by
adopting a single platform strategy for 2011 to 2012.”
