Class 4(4MB/s)
8GB~RM35(lowyat)
16GB~RM70(lowyat) other places, maybe RM5~15 difference

Class 10(10MB/s)
8GB~RM60
16GB~RM110~150

No need class 10 for phone I would say. Class 4 is enough even for full HD video

Kingston/Sandisk/Transcend all ok.

MicroSD slot in Galaxy W is under the backcover but still hot swappable. Just slot in, no need power off.

the processor can compete with desire hd
actually, we can use class 10 but i doubt that it will increase the speed dramatically and most users are having issues with class 10. class 4 is sufficient

Cameras would benefit the most from faster transfer rates. 

Not really. 5MP picture, even with my Nokia N82 (nokia picture normally have larger file compared to other brand like SE @ equivalent MP, don't ask me why though) also MAXIMUM 1.5MB. 4MB/s is more than enough. HD video bitrate max out @ 10Mbps (for phone) which is around 1.25MB/s. Sufficient too. Even 1080p playback also enough (~20Mbps/2.5MBps) Using class 4 won't be a big issue here.

bad news guys, Galaxy W's biggest flaw is the earpiece.

check the details here, got say...

I wonder if there's any possible way to fix it?
wei you guys watch HD videos won't lag the phone meh?

ya.    sad.
thinking to play gameloft games.
saw internet got some way to move to external sd. perharps after I buy it I'll try it. 

btw , does SGW have overheat issues as SG2 I9100?
since it's overclock to 1.4ghz.><
if heat less than i9100 will be better.
how do you feel about ur SGW for heating issues?

gonna go 1st Avenue tonight to see SEP.

But bear in mind. Even internal memory is high, but gameloft games that cannot install in external sd mean useless. Neo might have low internal but at least can move games to external sd.
because SGW have internal memory, internal SD (/sdcard/) and external sd (/sdcard/externalsd).
but Neo only have internal memory and external SD (/sdcard/).
and when buy gameloft games, data file default save at (/sdcard/), so when come to SGW, unable to install in external sd as directory is different.
Thus higher internal memory compare to Neo also useless.
unless rooting the SGW which most of us dont want.

*Correct me if I'm mistake as I HAVEN'T buy SGW yet.
struggling because of new 3 layers of memory structures. ><
