I bought a Yahama 800 with HDMI and never regretted it, for exactly the reason you cite. That's downstairs. The old Sherwood up here in the study is on limited time--it doesn't even have component connections, but I can stretch a rca jack from the computer to it. It's a mess; the next one will be wireless.
If you've got the budget for it, go for it, as long as you don't overdo it.
Myself, I used to allow one such purchase a year, as a reward for saving.
Now we can do it a couple times a year, but I don't really need much. I did get the wife a 4/3 camera, so maybe we'll splurge on a few more lenses.
