A number of trusted sources have mentioned to us and our friends that the iPhone is somewhat dissapointing... Especially for business purposes:
"It won't replace a BlackBerry. It's not good for text input. It's just not a business product."
Reports have shown that the keyboard was a let down. Keyboarding with two thumbs often registers multiple key strokes, resulting in a bunch of mistakes... And the text auto-correction only works well for simple words.
The touchscreen is also said to have required somewhat harder presses to register input.
I must say this is a bit dissapointing to hear as I had hoped for better things from the iPhone, but I'll wait to get my hands on one before I pass judgement!
