Hi, I am thinking of buying the Mighty Mouse... I want a wireless mouse without a dock base that uses bluetooth and Apple's mice fits quite well in those features. But, what the people say about it? I heard some that say it is great, the best mouse ever... but other tell me that it is overpriced and that the wheel gets dirty very easy. And other deep doubt is if this product will be updated soon... I don't know how old it is or how long is its life cycle. Can anyone throw light on this questions? I would appreciate a lot. Thank you very much in advance. PD: Sorry about my english.
