SE M600i comes with 60MB of internal memory and includes a 64MB Memory Stick Micro (M2) card with the phone. But I suggest to getting a 1GB card for bigger space if you want to save multimedia files on it.

Running Symbian OS 9.1 and UIQ 3.0, SE M600i boasts UMTS support and the usual business applications, such as QuickOffice to write, edit, and read Microsoft Word and Excel documents, and a PDF viewer. With this features, for me, SE M600i mixed my business with pleasure meanwhile I use it for listening music, video streaming, and games. And by using SE PC Suite application help me sync my e-mail, contacts, calendar, and tasks from SE M600i to computer. SE M600i organized my business in my hand easily.

And not just for phone call and business applications, sometimes I use SE M600i as modem by wired or wireless connection. Through Bluetooth I connected SE M600i to my computer and sharing files to other cell phone.

Its slim design looks elegant with comfortable qwerty keyboard and large touch-screen display. I think SE M600i is one of best pocketable smartphones. Using 3-way scroll wheel we can move up, down and select easily, going back by pressing back button on left side, using its @ button to open browser (but this can be changed to other actions in the settings), and the good one is we can use pen stylus to write faster than using its dual function keyboard.

Despite all its many features, the lack of Wi-Fi support and a camera sorely disappointing and sometimes it crashed once in a while, most while browsing.
