The Nokia 5233 had a 2.0 MP camera which was back in that time was the best one compared to the other phones.
The Symbian OS gave a good battery backup for almost 2 1.and a half day with pretty much all features working.I still use it along with my smartphone for this sole purpose only.
It is a multi-tasking touch mobile phone which was launched by Nokia having best speed but nokia 5233 give the best speed in 2G networks or 2G net packs and it was more best for other phones.
