If you want to know whether to buy a phone that runs on symbian or android
then I'd go for Android (in fact, I have gone for Android to replace my old
Symbian phone). If you want to know whether to develop for Android or Symbian,
I'd go for Android. In the last 1/4 of 2010 there were around 100 million
smartphones sold worldwide, by a small majority most of them were Android based
knocking Symbian in to second place with iOS and RIM falling way behind. That
doesn't appear anything particularly special until you realise that Android's
market share increades by 8 times in 2010 and is set to continue growing for a
while yet. Symbian's share dropped a little and I believe it's on its way out.

Android and Symbian are two types of operating
systems which are used in mobile phones. Android as we all know is a latest
version while Symbian has been here for a long time. So, which is the best
amongst these two? This is possible a never ending argument but let us try to
put an end to it.

1) Great processing power based on modern processors. Androids use Cortex-A8
based processors which deliver a much better performance than Symbians with Arm
11 CPUs. Excellent examples are HTC Snapdragons (currently with 2nd generation)
and Samsung Hummingbirds, both running at 1 GHz speed (versus 680MHz speed in
Symbians). The gap in processing power is even larger with the newest dual-core
CPUs based on Cortex-A9 architecture (like in Motorola Atrix). That makes
Symbians to fall even farther behind Androids.
2) Screen resolution. Androids use higher screen resolutions with 800(854)x480
compared to Symbians (640x360). This allows more details to be displayed on
screen, which is especially handy with web browsing (the extra information on
screen saves the trouble to scroll too much). Furthermore, the recently
announced Atrix brings even a higher qHD resolution (960x540)! That means 2.25
times more pixels on the phone display than those found in Symbian phones.
3) Memory (RAM). Everyone hates when the applications in a phone start to crash
because of low memory. While 512MB RAM is normal for Androids, Symbians have to
leave with 256MB RAM. Despite Nokia trying to optimize the memory usage, “out
of memory” messages still happen in Symbian phones. On the contrary, some
Androids reward you with even more RAM (768MB in Desire HD, 1GB in Atrix).
4) Graphics and games. Symbian devices use the Broadcom BCM2727 GPU, which
while seems to perform pretty well against the old Adreno 200 chips (Nexus
One), it falls behind the newest Android GPUs. Current Android devices come
with powerful GPUs based on Adreno 205 (Desire HD) or PowerVR SGX540 cores.
Furthermore, the newest Nvidia Tegra 2 chips bring even further boost in
graphics performance, that is said to show 3-4 times better performance than
Adreno 205 or SGX540! Nvidia has opened a special portal called Tegra Zone,
where the owners of Android Tegra 2 devices can enjoy high quality gaming (as
Nvidia describes the chip: "capable of extreme multitasking with the first
mobile dual-core CPU, hardware accelerated Flash, and console-quality gaming
with an ultra-low power GeForce GPU).
