Strange wireless problem in my office

We occupy 2 consecutive floors on an 8 story building. We have 3 standalone Cisco AP's here.

2 x Aironet 1252's are on the 7th floor (sitting on tables)
1 x Aironet 1142 is on the 8th floor (ceiling mounted)
All are running the latest IOS as of December 31st, 2010.
All are running w/ WPA-2 Personal enabled.
All are set to broadcast SSID.
All are set to use the least congested frequency (feature that autoscan's and sets the radio to the channel of least competition.)

I can stay connected all day long with no issue on my Lenovo W510. It seems most of the laptops that I personally send out (latest firmware/drivers, clean installs etc) can stay connected fine too (Win 7).

However, about 20% of our workforce is entirely Macbook based (these are newer models with 802.11n support), and another 25% run some distro of Linux as their primary o/s (mainly developers). We have a mix of XP, Vista (very few), and Win 7 (primary) on the other side of the scale.

Numerous people have complained to me about the wireless and not being able to stay connected i.e. they will get disconnected from the AP (still be able to see the SSID) and have to reconnect. This never happens to me on my machine, so I cannot duplicate it. This is MOST common with Macbook users even with the new Sandy Bridge ones. What can I do to help these guys? If it helps I can post up one of my AP configs. FYI, I'm doing all configuration through the CLI. I hate using the http server on the Cisco AP (very slow).
 
I do not know Apple.

On PC based Laptops, many time it is the Power Saving feature.

Uncheck the Network Card's Power Saving (I.e., do not let the card save power).
There might be some variations on where the Power saving setting is.
Here are few examples, YMMV, look around in your systems.
