You have 2 options:
1)k790i
2)k810i
k810i supports 3G whereas the k790i does not.
k810i has a secondary videocall camera.
k810i also has the most wierd keypads ever!
Whereas that of k790i is much more traditional and decent.
The current price of the k790i (as per the thread by krazyfrog) is around Rs. 11.2k
The current price of the k810i is Rs 13k with a 2GB M2 stick
The k790i comes with a 1GB M2 stick.
My friend has been using it since the past one month...
Absolutely no problems with it...
Excellent cam with an even better media player...
Interface is extremely user friendly.
Themes, games and apps are different for the k790i...meaning, if u try k750i themes./games/apps, they won't work that well...most of the times they wont occupy the entire screen.
The image capture time of the k790i is very less..Believe me, I've tried taking a snap of my ceiling fan (in ON i.e. running condition)in complete darkness and the phone could capture all the 3 blades of the fan accurately...
The best pic feature also adds a zing to the phone...
Imagine, u are taking a picture of a small baby...u never know when he'l give his best smile....so u keep the mode on best pic, try to make the baby laugh n start capturing..otherwise its kinda disappointing to take baby snaps
The phone has overcome the drawbacks of previous SE models..
For eg:when u press the media player button with the head phones not connected, it will ask u whether to turn the media player on or not.In previous models, the media player used to either just start off directly or in case of some models like the k750i, it never used to start..
Message storing capacity can be an issue..Though I am not too sure about this..
Battery life has always been a problem for SE phones..
If u recharge your phone everyday, then it shouldn't really bother u..
Another thing that may bother you would be...when u connect ur phone to ur comp, the phone will reboot..
Now this can be very annoying at times...
Once you have got a SE phone, u need to shell out a few more bucks to get its accessories...
The first and the most important one being the scratch guard..
That will cost u somewhere around Rs. 300/-
Plz don't go for cheap scratch guards...
Then, u will also need to get a Leather pouch for your phone..
That will again be a little harsh on your pocket...
Believe me friend, the phone is really worth its price..
Moreover, u can also try searching on 'tweaking the k790i'
You can do many things once u tweak your phone,...
The loudness can be increased, the message storing capacity can be removed...the menus can be changed, etc.
I've heard the following things about both the phones. Plz correct me if I am wrong :
1)There is no major difference in software between the 2 phones
2)The k810i has 3G and a video call camera (both useless in India)
3)The keypad of k810i is not user friendly. If u txt msg (SMS) a lot, then the keypad can be a problem.
3)The earpiece speaker of the k810i is uncomfortable for hearing..
4)The k810 is lighter and smaller in size as compared to the k790i.
5)The camera lens slider protection of k810i is more compact than that of k790i.
6)The camera of k790i takes superior pictures than the k810i.
7)The body of the k810i is
a fingerprint magnet. You really have to clean it every time u use it otherwise it looks a right mess. Whereas that is not the case with the k790i
8 ) The k790i comes with a 1GB M2 stick and k810i comes with a 2GB M2 stick(in Mumbai..this fact is confirmed)
9)Since the k810i comes with a 2GB M2 stick, it makes the phone slower than the k790i...(not too sure about this...donnow if it is valid only if u fill up the M2 stick upto the brim)
So, the choice is yours and yours alone!
