content: Not bad but as always ,it's hardly nary a teardown since we don't see the gutsI wouldn't bother tearing down such a thing since i would need extra "tools"*obvious apple hater is obvious*

This kind of voice is the LAST thing I'd want to hear after spending 12 hours in the lab.Quote from: sonicj on March 20, 2012, 12:55:26 amAnd here I sit with only my hardened steel pick.Regarding the tear-down, looks like another overpriced crApple cultist device, i.e. shiny but virtually useless to engineers.EDIT:Well, THAT didn't take long. They're already overheating for some users:http://www.tuaw.com/2012/03/19/some-new-ipad-owners-complain-of-over-heating/

content: I disagree. I always liked the child voice of the computer VI in Resident Evil 1 movie, that is as long it doesn't start nagging like a child or turn against you..but then again at that age it girls/boys voices doesn't differ much.As much as I like to bash on Apple, the iPad has surprisingly lots of uses. And surely is not just hype, it might do to places like iPhone did to phones. I worked in hospitals where it basically screams "iPad please!" or the library book search. Those keyboards are nasty!

content: Apple product teardowns are getting boring now since all the PCBs look bland and they design the things to be as easy to assemble (and as difficult to disassemble, it seems) as possible so there isn't much to look at.Unlike almost every other manufacturer I've seen they seem to omit the silkscreen on their PCBs, making it difficult if not impossible to repair/troubleshoot at the component level. Gluing it shut just adds to that.Quote from: SigEpBlue on March 20, 2012, 03:27:48 amLooks like "overheating" as in "warm". I saw a maximum of 117F which is 47C, well within normal electronics operating temperatures but might be a little too much for the users. To be expected for something with such a powerful CPU/GPU. Maybe they expect it to contain super efficient technology that hasn't been invented yet

content: Quote from: amyk on March 20, 2012, 10:13:56 amIf you have been watching , their A5x 1GHz dual core is hardly powerful at all . In fact , it's not even remotely powerful .You need a Qualcomm MSM8260 if you want to know anything fast , or the upcoming 1.5GHz quads .Oh and the original sensation and the galaxy S II ( the only android phone i know which overheats )even if they are clocked at 1.2GHz is only ever slightly more powerful then the TI OMAP 4430 at 1.0GHz .I know the differences , i have a Optimus Black , my dad owns a Optimus Black and my mom owns a Sensation .

content: Apple got a real wrench up the ass when it comes to product design.I had to replace the Hard Drive in my 24" 2008 iMac once. Taking it apart felt more like surgery then PC repair. The glass was held in by magnets and had to be removed with suction cups. Then there were torx screws around the perimeter, after taking the screws out and removing the aluminum frame I had to remove the LCD display which had a flex cable that nearly got riped off because I didn't notice it, underneath the LCD panel the power supply was unshielded and the transformer was less then an inch from the hard drive in question.On the plus side they used a double sided PCB for the power supply on the down side a technician less savy when it comes to high voltages could have gotten themselves killed trying to replace a hard drive.

The apple A chip family is a hunk o' crap .

content: We'd all like to see a teardown of her, but we all know that they use an attractive woman to lure in lonely geeks. If I'm wrong, please forgive my assumptions. I absolutely love seeing women that are actually involved in science and engineering. It's incredibly attractive and it makes me happy to see more diversity.If Dave was a busty woman, he'd get 100M views without a sweat.Nevertheless, I prefer Dave's enthusiastic and professional method along with his humor.

Seriously, mortifying.I wasn't meaning to be sexist as I have great respect for females in the technical industry. I'm just stating that us nerds can't resist a smart, sexy woman. Can't we all agree on this?

content: that was a terrible video, I don't know who it was aimed at but I just got the sense she didn't really know anything about electronics, it's kind of like the "booth babe" argument. people that would be interested in this type of video don't need some attractive girl to keep our interest. If you're going to get an attractive girl to host these videos then get one who knows their engineering AND has a nice voice like Jeri for example.
