I thought mt TV (which max resolution is 1080i) was the highest I could have gotten...  What the hell is 1080p?  Any difference?  I use old-school consoles on my hdtv so would the 1080p make them look even shittier than they look on my 1080i?  Assuming that 1080p is better.

1080P is the best at the moment.
Do checkwhat is your TV's true resolution.
Is it HD Ready 720 (720x1280) or Full HD (1080x1920)
if it's the latter I'd supriced if it could not do 1080P.

And crap your image looks depends on your TV's video prosessing chip.

Zapper, Super scope and other light gun games you can't play anyway  :'(

Oh and to answer your question

i means interlaced where the TV first draws every other line then the rest, where as p draws the lines in order.
I is left over from old TV times.
P has less flicker but difference can be miniscule.

1080i isn't the highest your TV can go. When your TV interlaces, it shows half the vertical resolution in one frame, and the other half the next. In all reality, 1080i is really 540p, 480i is really 240p. The Hierarchy goes 480i, 480p, 1080i, 720p, 1080p.

Now it makes sense to me.

For some reason I've always thought that the TV draws when interlacing half the vertical resolution 0F THE SCREEN and image first then the other half.
Like that the beam was too slow to draw every line in order, so they had to draw the lines in the alternating order to be able to draw in time. :-[

That is (more or less) what's going on.

480i and 240p aren't the same thing at all. If they were, you wouldn't see people going gaga over 240p and RGB and whatnot when it comes to old consoles.

Hmm, ok I am watching the NBC HD channel and if I hit the info button on my remote it displays a box that says:  1080i  HD  16:9.  When I turn on the CNN HD channel and hit info it says 720p  HD  16:9.  It must be 1080i though, right?  Otherwise all channels would read 720p?

Since the first part of your question was already answered I'll get you the second part. Your old consoles will not display in 1080i or 1080p. The resolution is determined by the source. Some systems looks crappier than others. I found that my NES, SNES, SMS, and Genesis don't look terrible. However, the N64 GameCube, Jaguar, PS1, Saturn, and DC all look terrible. Classic consoles are better of being played on a CRT.

On a side note, the original light guns will not work with a modern T.V. However, there are 3rd party light guns that will.

As I said before, the resolution is being determined by the source. Most HD channels are transmitted in either 1080i or 720p. So, yes, CNN was in 720p.

Owning more than one television is too much for me.  I refuse to use multiple televisions, hence the reason I purchased an upscaler.  The upscaler has two options:   to upscale to 720p or 1080p.  When I set the upscaler to 1080p, my TV displays a message "This Format Is Not Supported."  So, if I buy a 1080p TV, instead of keeping the 1080i, then I should be able to upscale my old consoles even better.

How big is the TV? because if its under 43 inches, 1080p and 720p are nearly identical to the naked eye. You say you have an upscaler, can you do some Before and After shots using various pieces of game hardware?

I wasn't suggesting that you get two televisions. I was just saying that they look best on a CRT, in RGB if at all possible. I don't imagine the difference is worth what you'll pay. I would only bother if you want to watch Blu Rays and you have around a 45" panel, as scarmullet suggested. I've never seen an older video game system upscaled but if it's anything comparable to upscaling a DVD the difference is VERY marginal. At least it is to me.

I'd love to see some before and after shots as well.

I think with HDTVs, it's even more important than usual to use the highest quality cables possible. Component, RGB Scart (with a component transcoder), VGA (in the case of the dreamcast), etc. The scalers built into most HDTVs seem to be quite unforgiving when it comes to signal quality. You should be using S-Video at the bare minimum.

Personally, I think all of my classic consoles using RGB scart look fantastic on my HDTV. SNES, Sega Genesis, Sega Saturn, N64 (modded), Sega Master System (Power Base Converter), all look quite nice.

Unfortunately it's also why I don't use my NES, since the best it outputs is composite without a difficult mod (which requires some very hard to find parts).

What the hell is RGB scart?  And what kinf of N64 mod do you have?

RGB scart's a european standard. RGB is basically the highest quality video signal you can get out of old game systems, it's practically the native format the systems work with. N64 doesn't normally output RGB, so I modded mine to do so.

To use RGB scart in the US, you need a transcoder to convert the signal to component. This is what I do.
