Since it's HDV, you'll need a computer with a couple GB's of memory, a faster Core Duo or Quad Core processor to cut rendering time and several hundred GB's of storage/editing space. Since it is HDV any of the HDV editors will work with the imported files natively as the format has been around awhile. Even the low-end Premiere Elements and other versions of some of the sub-$100 editors edit in HDV. Vegas Movie Studio Platinum is one I've used. The Platinum is the HDV version.
You can also shoot in HDV and import in SD if you're making DVD's for customers etc. But it's nice to have the ability to output in HDV if/when you get a Blu-Ray burner. I find it easy to store a box of tapes for future use since I don't have one yet. IMO HDV downconverted to SD still looks better than SD, one of my photographer friends who has a critical eye agreed when he saw some of my footage.
If it's anything like my 1CMOS Sony, it's not so great in low-light conditions. It can be stunning though if the light is good and the water is clear.
I've never heard of any particular issues with the HV-10.
