Ive had a xt10i for over a year now and I like it, so heres answers from my experience:
1) the mirrors are fine (its not refractor fine) I use a 7mm Pentax XW for high power (171x) no distortion there!
2) COL accuracy depends on the warp factor you get after centering your 2 alignment stars! Even with high warp factors my target was always in the FOV of my finder ep a 27mm Panoptic at 44x with 1.53°TFOV
3) My dark site is in a grassy field at 400 feet, as long as you first regulated the vertical stop knob the COL works fine even on unlevel ground.
4) TRUE be very careful with the encoding disk when mounting the OTA! a bent encoding disk means false COL readings!
5) I find the azimuth tightening knob with a telon washer works very well! I have a telrad and use some very heavy 2" ep's (35Stratus, 27Pan, 17Nag & 12Nag) tightening the altitude knob at just the right resistance dose not make altitude positioning jerky! But the teflon washer does wear down and has to be replaced every year or so.
6) Azimuth motion is fine when the scope is new, after time and especially observing in sandy & dirt fields the teflon pads (heads) get scratchy and must be sanded down or replaced with magic sliders or virgin telfon (ebony star), all works very well (as per the guy's on skyquest groups yahoo) I just sanded mine a bit and put car wax on the baseboard! works fine!
OK I'm no specialist to do telescope reviews! My experience is limited, but I think the intelliscope was the best deal I could have made! (But I am having wet dreams about owning a 18" Obession UC!  )  Hope this helps! Shawn
