Outstanding features: Samsung is undoubtedly a master when it comes to creating sleek, attractive slider phones.

Though the earlier phones failed to create an impact in the Indian market, the D500 changed that scenario. It has all the features and was touted as the world's best phone at the 3GSM expo. But it had no room for expanding memory so a successor was promptly planned.

The D600 excels in every aspect, be it looks, features, memory or camera. It has a 2-megapixel camera that gives a whole new dimension to this business class phone. It also accepts Transflash cards.

Drawbacks: Priced slightly priced higher than similar phones offering the same kind of features.

Final word: Pixcel viewer is an asset in a business phone. It allows you to view PDF, word files within seconds. Even a 20MB PDF file opens in less than five seconds.

Cost: Rs 20,999 (Maximum Retail Price)
