Check the ink capacity of the cartridges that come with the printer versus replacement cartridges. Secondly, flat panel tvs sound like a great alternative, except that a digital projector can push out an image 7 or 8 feet across while for the same price as a 32" LCD flat panel television. While the resolution is MUCH higher in a LCD flat panel, the 32" "regular" television I had in my classroom wasn't good for much other than taking up space in the corner (I taught Biology in a lab-combination classroom which was about twice the size of a normal classroom). My Epson came-over-on-the-Mayflower digital projector was much better for displaying information/videos to my students even if it was limited to the 48" surface of my Smartboard. And that takes me to Smartboards. Several people in my district and I have worked out the cost effectiveness of purchasing Smartboards, projectors, and computers for a classroom and we decided that placing a tablet PC and wireless digital projector is not only cheaper, but more useful for maintaining classroom management (e.g. walking those class traffic aisles while teaching). Also, the need for Airliners or Symposium hardware is eliminated because the teacher can hand the tablet to a student. Downsides to this model? BATTERY LIFE. The Toshiba m400s we have tested start with a battery life around 4 hours, but they don't stay there. For another $200 we can get an extended battery that adds 4-6 hours to the computer - now we are getting somewhere. But that added cost just dips into the money saved by eliminating the Smartboard. Also the weight of the computer is something to take into account. The m400 is a pretty lightweight machine but it begins to drag on you after a couple of hours (I haul mine everywhere I go). Our district provides a laptop to every teacher, so switching to a tablet is a bit pricier, but the prices have already started dropping (the last tablets I bought are roughly twice as powerful as the first ones and both batches cost the same price). Finally, we are utilizing flat panel televisions in areas of our new construction projects where a projector is overkill (i.e. conference rooms). Once the price of a 60" or larger flat panel tv drops below the price of a digital projector, I'll be a lot more interested.

Our district bought 32" televisions for every classroom. They are fairly ineffective. Nice to have but the resolution is horrible and very difficult to see. I do have a SmartBoard in my classroom. I like it but really fail to see how many of my teachers would benefit from one. We have a mobile Sympodium unit in the library. It is under utilized. I have been through three projectors in five years. A bulb will last about 6 months and replacement bulbs are impossible to find on older model projectors. I would recommend waiting. Do not do anything in the next year. Wait and see what technology will do in the near future. Anything done today will be out of date in three years. We bought VCR machines for all of out televisions. But I still have an eight track tape player in my truck... A side note on something similar. I was at Office Depot. They have a color laser printer for $250 after rebate. Four cartridges. At $90 each it is cheaper to buy a whole new printer then to replace the ink cartridges.

This is exactly the type of solution I am wondering if exists (minus the customization and the videoconferencing CODEC). I keeping my eyes out and will be making a couple of calls on Monday.

I'll inquire with Marci Powell, who I think helped with that acquisition and see if she knows....

You bring up an interesting idea and something to consider. Within the schools I work at, most administrators are looking right now at purchasing projectors, not for every classroom, but at the very least every grade level or subject area. Have you seen any flat screens on mobile carts that could be moved from room to room? I am sure something like this must exist, and I'd like to see how close in price the two are at this point.

I just see it as a more efficient means of bringing video and technology into the classroom. Sure, the price point isn't exactly there yet but it won't be long. The more I think about this, however, the more I think that projectors aren't the perfect solution.

I still find it hard to believe that when I hold a $300 bulb in my hand, I am really holding a small version of a car headlight. We have tried the flat panel idea, but a few things happen. Kids, being kids, like to poke them, and touch them. The screens are just not durable enough for the typical classroom where sharp pencils and greasy hands abound. I have seen some LCD's with a glossy overlay, but you then run into the problem of terrible glare and reflections. I'm sure we will see the day when whiteboards are replaced by video display panels (like thin-rear projected Smartboards). I would love one. Ron Wes:
