AT200 plus:
-Price nearly 100 EUR cheaper
-omap dual core sufficient for ebook reading and surfing and video chat and flash and video hd
-Easy 535g - with one hand
-good processing, chic design
interfaces HDMI, Micro USB
-display reflections sufficiently bright, with reduced manual adjustment to the level of Sony
-Good supplied (covers, screen protectors)
-extra configurable button for example to turn Auto rotate display (very useful when reading in bed)
minus:
-schlechte web cams (both): noisy room light, with movements very blurred - "sea sick" effect
Only Micro SD, no full sd - reason for the star deduction
The AT200 is wider than Sony with approx 0.7 cm. One hope was thus an entire PDF A4 sheet in the original mode (no reflow) is readable. Unfortunately is not the falll because the letters are variables in small font difficult to read (chiaroscuro effects in the letter).
AT300 plus:
AT200 + normal SD card + Tegra 3+ better sound + better battery performance
minus:
-many reports of processing problems (Display is on) - my test copy but had no serious flaws
-heavy, but is still well in hand
-web cam just as bad as AT200
display with "lichthoefe" ie with small bright areas on the edge, visible only when the display black, eg the ebook reading in night mode; Man, however, can live with it, it's a bit whining hochem level
-kaum vernunftiges supplied - such as a shell!
Sony Xperia Tablet S:
Is a bit smaller than the 2 Toshi, but very little, hardly noticeable. Is very good in the hand, can often be held with one hand
plus:
-easy
-good Webcams - it makes Skype really fun
-super display, for example, the black levels are much better than at Toshi (ie when Toshi is black a bit milky than Sony), also at small font sizes will remain the letters very readable
accessories you not find better than that of AT300 AT200 but on level
-normal sd card
-Tegra 3
display reflects a lot less in the default setting as the 2 Toshiba
minus:
-no USB device directly on extra adapter required (I'm waiting to be cheaper), HDMI as well
cover for power jack can easily lose man
-vorinstallierte Sony programs can not To uninstall, some nerves such as would be the new PlayStation Mobile verfuegbsr with messages, I'm supposed to look at that ... but you can ignore, does not bother soooo badly.
I chose the Sony opted for web cam and the associated Skype advantage. I can now run after the children here with the tablet through the house and at the other end of the connection Skype is still a usable image (still images, so if I use the FrontCam and do not move badly, are with Toshiba also good).
Read ebooks, surfing, photos and watch videos and movies all. 3
