I dont own a cell or sidekick, so I really dont care. If I had one, would I? Probably not. Thats what I have a laptop for. I am assuming here, but I would think I wouldnt be able to get everything out I wanted to, within the certain amount of characters each probably is given to you via cell or sidekick. I also know that I wouldnt be able to concentrate on what I was doing. But, as for those that do use them, more power to them. I just dont think I would or would like to play with someone using one. Id feel like I was left hanging because they arent using their normal computer. Its a different kind of effort to me I guess...
