I have a "travel" steamer--Jiffy Esteam something. Extremely bare bones--fill with water, plug in, wait for steam, steam garments, repeat as needed. I love it. I haven't ironed anything since I got it (but I'm prone to going with the wrinkle anyway, so that's not saying THAT much). The full-size one didn't seem necessary to me--I just steam clothes in the bathroom (have to fill the steamer up in the sink anyway) and hang clothes off the hook, shower rod, or towel bar. I also do travel with it frequently--I can fit it into a gallon-size ziploc bag--and it makes me much less crazed about packing for something like a job interview. If my suit jacket gets rumpled in transit (very likely in a carry-on) I can freshen it up without a problem.
I think Slate did a round-up of travel steamers fairly recently, which is how I picked which one I would buy (got it on Amazon, ultimately).
