I just...what...
I created an account, just so I could reply to this.
1.) If you're getting 30% battery drain in 2 hours with juice defender, you're using the wrong settings, or you were using your phone actively, which Juice Defender is mostly marginal on for improving performance
2.) Juice defender is brilliant, and I mean absolutely brilliant for helping with standby power drain loss. If you're on your phone actively, it's not really going to be doing much for you for the most part
3.) Driving is a common, necessary expense. If I could bike 300 miles and save a tank of gas, to get me a battery, I would, but it's not practical for most of us, so we fill up on gas and drive to and from work
4.) If you're spending $800 on a so-so laptop, you're either buying a MAC, or you're spending far too much
I got a quad i7, HD Radeon 6770, 8 gigs of ram, 500gb 7200rpm HD, 17" 900p, blu ray player, laptop, brand new, for $850 shipped. Check out slickdeals.net and subscribe to notifications on laptop deals.
5.) How does having a Corvette help this analogy, or having an extra battery prevent you from killing yourself?
Some of us prefer to go the frugal route, and with Juice defender and autokill, I can get a full day of moderate to heavy use out of my triumph between charging. No need for a spare $50 battery. If they came down to $15 or $20? Sure, I'll pick one up. But not for $50.
Still, if Seido makes the extended life battery (and I've heard rumor they will in 6-8 weeks), then I'll spring the $80 or whatever it ends up being to grab that, as it's more than a spare battery to swap to (and I had it on my epic and it completely changed how I used my phone).
