I think that it already exists fro some devices, Apple iPhone and Nokia N95 if memory serves me correctly.
Chess.com Mobile

Well I have an iPhone and there wasn't a mobile device mode that I saw. Then again I didn't look very closely....

I have an iPhone and I made a move this past weekend from it just using the normal site. It was very slow and kind of buggy.
Recently I got an internet plan with my mobile device and when surfing the web via my cell phone I've noticed some websites have a mobile device mode to make loading the site easier and less time consuming for the phone's limited capabilities. But when I went to chess.com I believe there was only a regular site mode.
So that got me thinking about how maybe somewhere in the distant future, maybe the chess.com staff could figure out a mobile device mode for this website. It's not like I'm dying for it, just an idea that maybe the staff would like to try out. Anyone else think it's a good idea?
