I got the Samsung Galaxy 3 here for just 6,100 baht. If you want to get a decent Android phone for a reasonable price then I would say this is the model to get. All the features you want with only these two drawbacks:
1) No 'double-touch' input (do you really need this?)
2) Currently stuck at Android 2.1 (they definitely will upgrade to 2.2 they tell me)
Sure, if you have lots of bucks and have tried the Android out and really like it then I would say go for a more elaborate phone. LG looks to be getting better and better all of the time but are they as good as Samsung?
