It's a daunting task to wander through the maze of data/video projectors and pick one you think will make everyone in your office happy about using it. Our office uses InFocus, Hitatchi, and Dell projectors. They range from $1,000-$5,000 in price. The most expensive are the brightest and are not considered portable since they are designed for large rooms and not many people would want to carry them around. The InFocus models are our most portable and they have served us well for over 6 years. The typical portable projector burns at 2000 ANSI lumens with a max resolution of 1024x768 and the lamp has a 2,000 hour life expectancy. Those specs are still typical of most portable (under 7 lbs) projectors. If you are shopping for a portable projector, here are some models to consider: Dell 2400MP is very popular. $1100. I see them at conferences and UCD all the time. The resolution and lamp life is the same as most but it has 3,000 lumens (is 50% bthan most). If it is within 16' of the screen, it will be bright enough to leave the lights on in the room. http://projectorcentral.com/Dell-2400MP.htm 5.5 lbs. (Lamp replacement $329) I have one caution for those making the selection without expert advice. Sometimes you'll find what seems like the perfect projector but in reality the lens may require the projector to be 20 feet from the screen because it is designed for very large rooms or even projection booths in auditoriums. Keep an eye on "throw distance". You want the minimum to be within 7 feet (projector to screen). For each projector listed at the ProjectorCentral.com website, there is a distance calculator which I find very helpful. . Mike Poe, Media Services Manager, ANR Communication Services Dell 5100MP
Dell replacement lamp
With portability comes trade-offs, usually in brightness (lumens) and image size. Nearly all portable projectors only have the same 2,000 hour lamp life so no matter what you buy, you'll need to replace the lamp in a few years (depending on usage, of course). And they are not cheap! They typically cost between $300 and $500 to replace and it is not likely that will change in the foreseeable future. Most last 2-3,000 hours and some for the latest models are made to last closer to 5,000 hours, but those are neither portable, nor cheap.
The InFocus IN36 is very similar to the Dell and costs around $1400. 5.2 lbs (Lamp replacement $500)

InFocus IN10 is brand new (Summer 07). $1250. It only weighs 2.4 lbs. The brightness is actually less than most at 1800 lumens, but the lamp lasts 4,000 hours. That's the trade-off, longer lamp life=not as bright. It is small and would work best in small group settings.

InFocus IN42 model. $4,000. Not so portable, but if you really want a bright one, there are projectors with 3500 and 4000 lumens. They weigh 13 lbs and 16 lbs respectively. I wouldn't want to travel much with those since it would require another rolling suitcase to get them around. It's not so bad for a car trip, but I wouldn't want to bother with it at the airport. Also, the lamp life is the same 2,000 hours and because of the brightness, will cost at the high end to replace ($500 ).

Need a webcam for Breeze? Why would you?
Besides having your face appear on the other party's computer there's another thing it provides. A webcam with a built-in microphone eliminates the need for a mic on a stand or attached to a headset. It's one less thing to carry around. There are some really cheap (less than $30) webcams that don't have built-in mics, but they tend to include a headset with a mic.
This link is CNET's review of webcams sorted by Editor's Rating: http://reviews.cnet.com/4566-6502_7-0.html?sort=edRating7 desc
You'll note that the highest ratings are for older webcams. I have purchased for my office these since September 06 (all have built-in mics and their bases are designed to hang onto a monitor or laptop lid):
Logitech QuickCam Pro 5000 (for my desk)
Microsoft LifeCam VX-6000 (for two desktops and two laptops)
and also a Logitech Quickcam Communicate Webcam (for a desktop)
At home I use:
Logitech QuickCam Communicate STX Webcam (my wife's laptop) and a Microsoft LifeCam VX-6000 for my desktop.
The bottom line--they all work. The Logitech webcams are higher quality but they had a bad driver in early '07 and there were compatibility problems. That's been cleared up by a new driver release. The Logitech 5000 is a bit big to carry around with a laptop. All of the Logitech webcams have the same body style, but vary in size. I prefer the Microsoft LifeCam or the Logitech QuickCam STX for mobility. They are both smaller and easier to pack.
If I were to buy a webcam today just for a laptop I would get the Logitech QuickCam for Notebooks Deluxe.
The Microsoft webcams above work with all our Windows machines very well, but the ones we have do require manual focus. In some reviews, that's considered a plus. But it is hard to do with a webcam on a desktop display that may be beyond an arm's reach. If you lean in to turn the focus ring, your face (the thing to focus on) is no longer where it will be when you are using the camera.
None of these compare to real digital cameras for stills or camcorders for video, but someday the resolution will improve enough to be useful in that way, but not yet.
Some of the ratings are based on "video effects." I've found no use for any of them except for a few minutes of fun upon installation. I haven't found any use for them professionally.
