Judging by the huge success that the Nokia 5800 XpressMusic has been so far worldwide, word has it that Nokia will be introducing a capacitive touchscreen upgrade to the same handset in the near future. This is different from the resistive touchscreen that the 5800 currently enjoys, where pressure is required to navigate, making a stylus the preferred choice of input at times compared to a finger. The whole switch is meant to help the 5800 keep up with the iPhone as well as newer touchscreen phones from Korea including the LG Arena and Samsung Omnia HD. Nokia has lined up around 2 million of upgraded handsets to be shipped between May and June, with word of the upcoming N97 receiving a similar treatment as well. No idea whether the final price will be affected though with this upgrade.
