I am making a presentation for an organization that has a digital image projector and would like to utilize it, however I don't have laptop. Surely there are other less expensive devices that would do the job.
Please let me know my options.
Some of the better cell phones have cables available that will link to the projectors.
But, you could still get a decent laptop for $300 u.s. - it's called "netbook". I can't imagine driving a projector for a presentation much cheaper than that.
