Please tell which one is better.. Nokia 5610 or N81 ??

I use music features... play games... but the problem is 5610 has a symbian s40 platform whereas N81's got s60 platform.. which one's good and might last longer without having to upgrade for ... maybe 2 yrs or so ??... i need a phone which i constantly fine tune.. install/uninstall softwares and applications...previously i had nokia 3230.. using it for abt an year....finding it too outdated.. hangs very often... even after using 2 gb card....i don't use the camera very much though... price range of about Rs.10,000-Rs.16,000... can exceed by a little.... any other model/brand suggestions.. please help me... thanx in advance.....

All the S60 phones hang ..... You can instead buy a S40 .. The 5610 is a good choice ... The 5610 will defnitely last longer than S60 phone ... the sound quality is equal to N81 ... Camera is 3.2 Mp ...Very Clear .... Video recording resolution is 640X480 ... There has also been some problems in the 5610 that the slider comes off in some phones .... But nothing can't last long like the sony ericssons and also the sony never hangs ... U can have a look at the Sony Ericsson K810i or K790i ... Sony ericsson K810i is a good phone in that price range (Rs 13,800)... . extremely good 3.2 Mp camera ... has a xenon flash (even pictures taken in dark will look like it's been taken in the morning) superb battery (10hrs talktime ,, 490 hours standby ) .... though the sound output is a bit low in music player ....... the headset is superb with the MEGABaSS Feature .... the K790i is the same (almost) except the 3G feature .... the sony ericsson's have extremely good screen clarity ... the sony's battery lasts longer than any nokia phone ... i owned the K810i a while back and i charge the battery once in 4 days but the N73Me Which i use now lasts only for 1and half days ... the other brands except SONY and NOKIA aren't that good ... so i would recommend you the K790i or The K810i ... if you could extend u'r budget to Rs 19000 .... Buy The SonyEriccson K850i .... the best phone ever ... has walkman 3.0 player ... touch sensitive buttons .. 5.0 Mp camera ... 16X digital Zoom ... Automatic Camera Shutter .. A Xenon Flash And Three LED flash .. Cybershot 2.0 ... Shake Control .. 2GB card ... Flash Lite 2.1 ... 9 Hrs battery talktime ... since u've mentioned that you keep on installing and uninstalling ... the Nokia's will start getting hung often but the sony's wont ... you can always rely on sonyericsson

the N81 is top notch for everything im a proud owner
