DisplayMate, a company specializing in scientific display testing and calibration, gave the Retina iPad Mini third place in detailed lab tests of three leading 7-inch tablets, criticising Apple for “really bad planning” for what it considers to be out-dated display technology.

And finally… the iPad mini with Retina Display unfortunately comes in with a distant 3rd place finish behind the innovative displays on the Kindle Fire HDX 7 and new Nexus 7 […]

All of this reliance on IGZO is really bad planning… Right now there is a readily available display technology that has much higher performance than IGZO. It’s Low Temperature Poly Silicon LTPS, and it is used in all of the iPhones and in all of Samsung OLEDs (so it’s available in large quantities). Two innovative tablet manufacturers, Amazon and Google, have significantly leapfrogged Apple by introducing Tablet displays using LTPS (in the Kindle Fire HDX 8.9 and the new Nexus 7), and they are significantly outperforming the IGZO and a-Si displays in the current iPads.

Unfortunately, iFixit described the process as an “exercise in disappointment,” noting the iMac’s new thinner design introduces new hurdles for repairability. Most notably, the device’s glass and LCD are now glued directly to the iMac’s frame, while accessing the RAM, CPU, and hard drive will now mean having to remove the entire logic board:

The late 2012 iMac 21.5″ — code-named EMC 2544 — is an exercise in disappointment for us. We were quite worried when we saw that super-thin bezel during Apple’s keynote, and unfortunately we were correct: the glass and LCD are now glued to the iMac’s frame with incredibly strong adhesive. Gone are the lovely magnets that held the glass in place in iMacs of yesteryear.

A few things noted in iFixit’s highlights: a new rubber housing that “dampens the vibrations from the spinning hard drive,” a new single fan layout, dual microphones, and a 5mm thinner LG made display. Those are some of the highlights of Apple’s new design, but iFixit is scoring the new iMac as a 3 out of 10 (down from 7 last year) due to the many issues with repairability. Here are just a few:

Smartphone parts supplier ETrade Supply just posted alleged leaked OEM parts of the iPad mini’s nearly 8-inch LCD screen and 4490mAh battery.

Apple’s much-discussed iPad mini is set to unveil at the company’s media event next Tuesday, and today’s parts pictures possibly confirm earlier reports and give a sneak peak as to what to expect from the folks in Cupertino.

The device’s display is “about 162mm in length and 124mm in width,” according to ETrade Supply, with a ratio of 4:3. Labeling on the back also indicates LG Display manufactures the part.
