hi guys i decided to keep my iPad WiFi with the following reason:

1. i don't use 3G often to surf internet. paying monthly fees for 3G data services (like maxis/digi broadband) seems not worth it.

2. even if i going to use, it's going to be very light surfing or emergency need, i installed joikuspot on my N95 so my N95 is plenty as a tethering device and it's even better cause i can use it with any other devices, and i don't need to spend money on MiFi. i also found out the huawei MiFi can't be charge and access at the same time, you need to drain the battery then only can charge. everybody know you can charge your phone while doing anything with it...

3. if i use the 3G service, my top priority is to download lots of youtube video and use them for educational purpose, which is a no go because:
A) all 3G "unlimited" access are all BS as they all have bandwidth capping and limited quota and i'm going to finish the quota very quickly (Celcom unlimited quota is super expensive), i'd rather use maxis day pass 500MB a day for RM8 (cheaper than ordering a cup of coffebean/starbuck coffee!).
B) 3G data services are not as stable is it seems, youtube over 3G is pretty unstable and i don't want to be frustrated in the middle of teaching. i rather doing all the downloads at home and use them on the lessons.
C) the only place i use for educational purpose is at uni, which has wifi, rendering 3G useless.
so if anyone of you facing the same dilemma as me, hope my analysis will help you to decide and save more money.
PS: thanks for the folks who were interested in my iPad, and sorry to disappoint you with my decision.
