Possibly in the wrong forum (sorry!), but I have a problem I thought you guys might be able to help with. We've just furnished a new media suite with 31 iMacs - current gen, wireless keyboard and mouse, and no problems with anything (server and network up and running like a dream already ahead of a September launch in a new facility). It's essentially a classroom, that will get probably 6 hours use, 5 days a week. I'm worried about batteries - with the nature of these things, all the batteries are gonna run out together - so 93 batteries needing replaced. Anyone have any experience with dealing with this? Are large scale charging solutions available, or docking stations that the keyboard/mouse can be put into each night? I've had a look about, and the wireless mobee 'magic bar' type things are brilliant, but expensive (yes, I realise the irony in spending £XX in building the suite and not spending a few more thousand on chargers, but I've just inherited the suite and didn't design it (I'd have asked for wired peripherals: knowing the type of student likely to be using the suite, equipment being tied and/or nailed to the furniture is preferential)). i can't seem to find an AA charger with greater than around 10 batteries capacity either, and having 10 or those lying around isn't really plausible either. Any thoughts/ideas gratefully received!
