Would like to add two devices since obtaining HDMI IV: a wireless keyboard

Question

Secondly, I would like to have headphones to have capability to listen tv without disburbing bed partner. I see apple wireless keyboard requires blue tooth usb dongle which costs as much as keyboard, looking at a Kensington wireless keyboard which uses that other technology. Excuse my ignorance.
Do I need to buy both blue tooth and beamed to headphone as my mac doessn't have internal bluetooth. I use Belkin Wireless currently b not n. I found a site with great reviews for 802.11n Mac USB Wireless Adapter, which is n . But pricey. That may be ok as i don't want to go backwards. my systems is used by four rooms wired and wireless and I also want to buy a wireless adapter for an old G3 so it will work in my grandkids house across from kitchen to back two bedrooms.
Can anyone advise which keyboard: i don;t like feel of new Mac flat ones, it slows down typing, I also like white. PS I have a great $1245 Kensington Trackball. So I don't necessarily need combo unit except for the grandkids g3. Iknow this is a big order. But i spent all day learning terms and getting not much done online. Thanks in advance. New HDMI and switcher trying to network an old G3

Answer 1

I am asking about my G5 desktop 1.8.
You asked the right question but in the wrong forum. This is the GEE-FOUR area. That's is why no one is answering other than me, who realized you would benefit from moving your post and offered help to relocate it. I provided the link to the G5 forums previously. I'm sure that, if you post there, you will get help from people who use and manage G5 computers on a regular basis.
From your profile, I see that most of your other posts are in the proper G5 forum, I remain confused about why you insist on getting this question answered in the GEE-FOUR forums, and why polite help offered made you angry.
These are user-to-user forums, not staffed by Apple employees, and everyone volunteers their time without hope of remuneration. That's why the forums are organized by model; people with common equipment types can share ideas and help with common problems. Your computer does not match the equipment and experience base of the forum in whcih you posted.
Misplaced posts are common here due to some confusing labeling of forum areas. However, someone getting mad when politely told they are better served by reposting in the area matching their computer model is NOT common.
