Is a Galaxy S2 or S3 worth buying?

I have the Galaxy S2 & i must say that am in love with it.. It's just like a mini-laptop & the apps are great.. Internet is cool to use as well as it has a wide & clear screen. I used to have the same problem as Mike with the battery though, until i downloaded this app: "Battery Saver".. I charge my battery every 48 hrs now, if i dnt play with the mobile whole day that is.... I believe it's totally worth the price n it has just the same apps as S3 or any iphone for that matter....

I have the Galaxy S2 it is fantastic piece of equipment, lots of useful Android apps too. Two problems that I have with it: (1) the battery drains too fast and I need to recharge daily, (2) the Android version is 2.3.4 and Samsung still have not released the upgrade to Android 4 version via Kies.
If I had known about Galaxy S3 coming I would have waited. Go for the S3 if your budget allows.

My brother has a Galaxy S2 and it's awesome(better than iphone) :p
But I don't know about S3..

both s2 n s3 gots advantage n disadvantage! it depend what are u searching for exactly ! the problem with samsung phone (s2,s3) it is not perfect for gaming as the phone heat a lot n drain ur battery! due to high performance with these two phone the need a bigger source of energy that is a battery over 2500mah would be okay :) as u can also use extended battery
i use both s2 n s3
