Since all TVs/Monitors/Projectors have had HDMI for some years now, i think it was a wise choice. IIRC there is still composite out for those stuck with only analogue connections.
The thing is the digital-to-analog converter would simply add too much cost to the device. A lot of these kinds of boards don't include VGA output because analog is (relatively) expensive, compared to digital.
Not sure where you are located, but in most bits of the US (and many other countries) you can find a small used monitor on Craigslist that has a DVI/HDMI port relatively cheap.
