Just a newbies observation here. I got the MoKo Ultra Slim Lightweight Smart-shell Stand Case for Google Nexus 10 inch Tablet by Samsung, RED (with Smart Cover Auto Wake/Sleep). My husband got the Poetic HardBack Protective Case for Google Nexus 10 (With Auto Sleep/Wake Function) (3 Year Warranty by Poetic). Now we just got these to cases a couple of days ago and here is what I think.
MoKo-very thin light weight but I wouldn't drop or toss it around. This case won't offer that amount of protection. Good for bag or backpack. It snaps in quite easily but it's very difficult to remove, which is not good for me but great for the Nexus. This case has dedicated cut outs which allows easy access to the power, volume, headphone, USB, HDMI, but does not have a dedicated cut out for the pogo. The case must be opened to access this connector. I find the magnetic closure to be acceptable and agree if not careful can scratch the screen. Love the auto wake/sleep feature. A few people complained about the odor, which I didn't notice. Overall a sturdy case. Materials used to make it are okay probably will not hold up well with daily usage(only time will tell) but for the price and lifetime warranty it was well worth it.
Poetic- bulkier then the Moko (which we knew before purchasing), which my husband likes, but still won't offer the protection if dropped. Snaps in easily and feels secure. Very difficult to remove which is a problem when you need to repeatedly unsnap the Nexus from the spine in order to use the self-standing feature. Husband feels this may wear out the supports that hold the Nexus in place with constant use. It has all the dedicated cut outs for power, volume, headphone, USB, HDMI, including the pogo. Husband also loves the auto wake/sleep feature. Magnetic closures are very secure. Like the MoKo my husband feels the material over time and constant use will wear rather quickly, but again for the price and 3 year warranty it was worth it.
Once again it's all a preference. I like my MoKo for being thin and light weight. My husband likes his Poetic for being a little more bulkier. Otherwise they do what they're suppose to do, protect our Nexus.
Hope this helps someone.
