@ Linu: I'm sure there's still people using 98 right now, they've got Vista and XP to choose from if they were to upgrade. And Vista was released 5 years after XP, so it makes sense that a new OS would be coming in about 3 year's time.
Assuming the average rack leaves 0.5" for each CD, 150 CDs would fit in a rack about 6.25' tall, I'd think most people have at least the 2 cubic feet of space required for that.
I'd rather have $100 extra than 2cu.ft. extra.
@ BuckeyeFanatic25: Severity is a major issue. A lot of people try to argue against Firefox by saying it "has more security holes than IE", but they fail to point out the Firefox's "security holes" are insignificant and basically non-exploitable, where as IE's bugs are gapping holes mostly concerning ActiveX.
I personally would rather have my updates small and frequent than delayed and huge.
If they can get it up to 1:1 and run the device purely off the solar panel, that would be a major improvement, and also wouldn't slowly kill your batteries through continuous charging/discharging as long as the sun is out.
