I received this a little over 10 hours ago, 2 days before the earliest "expected delivery" date, so brilliant service, and have spent the day putting the tablet through it's paces. First appearances, It's fast, not even just for the money, but genuinely slick. It's a little plasticky, but it's well put together and feels solid. The screen is responsive and bright, the resolution isn't amazing, but is more than sufficient to read anything down to about 5 point font, so more than good enough for using the tablet as a kindle substitute. ICS is beautifully intuitive and fast OS. I've installed the BBC Iplayer app, (Flash 11.1 is pre-installed on the tab), and it works perfectly, no sound-sync issues or video stutter, which is impressive considering the price.
I've also been busy downloading all the apps I had on my previous tablet (the previous generation resistive edition of this), while checking emails/facebook/twitter, multitasking quite heavily for a single core, but this kept up well, with only very occasional momentary pauses before a click responded, so very impressed on that count. On the subject of emails, the on-screen keyboard is the ICS standard one and is easy to use, and more than sufficient for browsing easily with/writing short emails etc.
Then, having set it up for my everyday usage, I started testing the performance, which of course meant gaming. I installed temple run (surprisingly CPU heavy, often causes my friends Nexus S to hang), and it ran perfectly, without lag. It did romp through the battery (the table arrived with 72% charge, lasted about 4 hours with wi-fi running constantly, fair usage) a bit, but that's to be expected. The table is currently charging, so I'll try a run down from full battery and update this then. The forward facing camera works well with skype, tested a video call to myself using a friend's account to test the quality, and it's as good as the inbuilt webcam on my laptop (HP Pavillion dm4). The inbuilt speaker isn't the greatest, but then it'll hardly be used, since I'll mostly use this on the train with headphones. the inbuilt apps are fairly good, but thanks to fully available Play Store, there's a choice of hundreds of if you disagree with them. I also pace-raced against my sister's 7" Galaxy tab, launching the same app/downloading etc, and found that (probably thanks to not running a custom-build android, this runs pure ICS), the M010s was often faster to respond.
Overall an utterly amazing piece of kit for the price, I would recommend this to anyone who wants a good small tablet but is unwilling to fork out for a more expensive branded model.
Update: I've now had this for a couple of weeks, and continue to be impressed. I've been using iplayer a fair bit, and I'm still surprised by just how well this tablet can stream video (both youtube and iplayer). I've found that the battery life with wi-fi on constantly and the screen turned up to full brightness is usually about 5 hours (there's a very good in-built battery use feature in ICS, which lets you keep track of what's using power easily). Without wi-fi, I've managed to stretch it to almost 8 hours use with the screen brightness right down. Also on the theme of battery use, locking the tablet reduces battery consumption to a minimal level, as with far more upmarket tablets, meaning that this tablet can (in my experience at least), be left turned on ready for immediate use, but locked for hours on end without draining the battery in much the same manner as an ipad. So after two weeks of using this, I'm still very pleased with it.
Further update: also, on the Google maps issue with black screens, if when google maps requests using gps to improve your location service you deselect the option and just use wi-fi network location, then maps works perfectly. Wi-fi location (at least in urban areas) can pinpoint you to about 20m radius, so is more than good enough for getting directions.
