Nokia has also made some slight revisions in the designs of the Xpress-on covers, where removal of the back cover is now done by pressing down onto a tab at the top end of the casing. Traditionally, all Nokia phones with Xpress-on covers requires the depressing of a button on the back cover, which can then be slid off and subsequently allowing the front cover to be lifted off. On the 2100, the back cover also comes off via lifting, and is actually easier to remove and replace than covers found on the 3310.
User Interface & display
The 2100 retains a similar look and feel of other black-and-white-screened Nokia handsets, but you may realise a slight difference in the type and size of the typeface used on the screen (in other words, the font for the text display). On most Nokia models, you could only fit up to nine numbers on a single line before the digits start appearing on the row above. For the 2100, ten digits fit comfortably on a single line - and not sacrificing readability either!
