hi friendsI hav been using this phone for 6 months. I will give a brief comparison and u guys decide which phone is real value for money. The main features are as follows.design : external design of x700 is gud but i feel the menu design could have been better it looks like a low end phone. display : x700 has bright display with 262k colors. Phone do not supports themes v can use only the default skins. skins arent that gud n the white background never changes. on applying skin only a small portion of the screen changes. it can never be a replacement for themes. K750 supports themes. Also he readability of the screen is not gud in direct sunlight. There is no option to zoom wallpapers n other images in x700. only the pic taken by the cam can b zoomed.camera : it has got 1.3mp camera. gud enough to take quality photos. but the cam doesnt produce actual colors. k750 wins here bcos it has 2 mp cam with autofocus and flash. x700 is useless in low light situations because it doesnt have night mode also. The phone manual says iso settings help in lowlight but its not at all true. video rec is better in k750. compared to the photo quality of x700 video is not at all gud.mp3 support : x700 has dual stereo speakers n it provide gud clarity music. But again k750 with single speaker is able to provide better sound volume.bluetooth : bluetooth data transfer is really fast and it hasa no infrared. K750 has both.FM radio : clarity is gud in both the sets. there is no option to record fm and calls in x700 in the menu but a secret code is there wich enables these functions. if the phone has the capability y didnt the samsung guys included it as a menu function. if any one needs the code i’l post herevideo playback : x700 supports 3gp and mp4 format. it can play videos in 176x144 resolutuion only where as k750 can play in fullscreen.software compatibility : k750 supports applications better than x700. some popular chat applications didnt work in x700( nimbuzz,implusetc). but there r many games available. opera mini browser works well in x700 but hangs sometimes.browser : web browsing is better in x700 and downloading is extremely fast.memory support : memory can b expanded using microsd card. shop guy said it supports 1gb but its nowhere mentioned i think it supports a max of 512. whereas k750 supports upto 2gb. But sony memory stic is costlier than microsd.The only reason i brought x700 was bcos of its price. it costed abt 1900 less than k750 at the time of purchase. in my opinion k750 has better feature set(like video DJ to edit videos) compared to x700. also the price of k750 has dropped to 8300(not sure whether its still available). If there is any mistakes x700 fans pls forgive me!
