Using a savings interest rate from a bank for the discount rate? Ouch. I'd go with a 10% mutual fund.

I like you already. I suggested one's local bank savings interest rate simply because it's readily accessible/available to the general population, who may not have a wide number of financial instruments to choose from.

I don't currently have a cash outflow for each option. This will be my first console since the original Playstation.
The options I was referring to was simply 360 vs. PS3 in terms of price. But here's the quick and dirty analysis that you asked for earlier:
I'll do the easier one, my #2, feature for feature, first:

This one's easy.
Price of 360 + HD-DVD drive + online gaming for 1 year = 400+200+50 = $650
Price of comparable PS3 = $500
I'm not even going to waste my time discounting future cash flows (annual Live price). The PS3 is cheaper right from the get-go.
If I get a little more detailed:
Price of Elite + HD-DVD + online gaming for 1 year = 480+200+50 =
$730 (Edit: Not $650! Whoops!)
Price of PS3 + 120 GB HD (from Newegg) = 500+53 = $553
The results are still clear on the feature-for-feature front.

1) if you're interested in online
Now for the slightly more complicated costing.
Option 1: 360
Year 1 cash flow: 360 + online gaming = 400+50 = 450
Year 2-5 cash flows: online gaming = $50 per year for 4 years
Option 2: PS3
Year 1 cash flow: PS3 = $500
No future cash flows (online is free).
Discount rate: 3.5%
Option 1 present value = -$450-$184 = -$633
Option 2 present value = -$500
The PS3, yet again, is the cheaper option.
Sensivity analysis:
Using a discount rate of 10%, Option 1 = -$608
Disclaimer:
Now, if one is just interested in simple gaming, with no online, no movies, no nothing, then the 360 is by far cheaper ($400 compared to the PS3's $500). One might also try to argue that Live is a better experience and thus worth the $50 per year to be allowed to game online (something you can do for free on the PC and PS3), but this is certainly debatable. Most PS3 games go online already, and the experience is more than adequate (e.g. R:FoM, with 40 players and virtually no lag, could reasonably be considered a superior experience) even before the PS3's online announcement. But neither of those is what I'm talking about - I had just pointed out that saying the PS3 is overpriced while not mentioning anything about MS's Xbox 360 (especially those rare nitwits screaming at the same time: PS3 is overpriced! Live is teh awsum!) is disingenuous, bordering on dishonest.
