Humble opinion ahead, if you don't face any quality issue, then the Meizu M1 Note is pretty good at the price selling.
It is faster than Meizu M2 Note, and of better quality than Lenovo A7000 Plus, which has similar spec.
The only worthy upgrade would be Xiaomi Redmi Note 2, which use a higher end processor, and upgraded the graphic chip too,
Mediatek Helio X10, but it is still not officially available at Malaysia. Won't recommend you buy AP set.On usage wise, it is depend on what you really need.
Overall, Meizu M1 Note has a good camera, good battery life, and good screen.
For some easy comparison, it's performance is better than a Samsung Galaxy Note 2, but loose to Samsung Galaxy Note 3.
The only downside is it don't has expandable memory, and the processor's graphic chip is not high end enough for today standard, you may notice the lag on playing high 3D graphic game, but still playable.
You can turn down the graphic setting to make the game running smoother.
Meaning, if you can live with it's only 16GB or 32GB
memory, and not playing any high 3D game like Asphalt 8, Real Racing 3, Modern Combat 5, then no point for you to consider an upgrade.
It is a never ending comparison, where in future for sure there will be higher end phone with similar cheap price available on the market.
Meizu n1 who said that Modern Com. 5 not really good? it's just lagging gimmicks dude...
as far as i know that , MTK are using MALI series and even Intel are smart, they go for PowerVr SGX and meanwhile, Qualcomm Adreno always called as "mobile of the AMD Radeon"
2nd. got money, it's depends on the buyer's only who said so AP set aren't bought for values , it's depends on your luck dude
so many of my phones from Kr/HK/EU or bought from 1G didn't face anything..
