I don't think the lack of image stabilization is an issue as most camera makers recommend you turn off IS when mounting a camera on a tripod. Something to do with the vibrations being too small for IS was intended for which can make the camera introduce its own shake.
Reading that review it looks like the scope was announced sometime in 2008 which means it must have been in development for a while before that. We are nearly in 2011 so the technology is maybe getting on for 5 years out of date. The main issues for me in the review were the poor battery life, I think the user said around 100 images on a battery, no HD video but instead quite a low resolution AVI and slow to write images to the SD card.
There's a gallery of photos here. The one that opens up on this link shows some quite bad CA. I noticed a lot of the brighter images had blown highlights too. A lot of the images are acceptable but it certainly doesn't produce images worthy of the price tag.
