Executive summary: I forgot the last time I used my Nexus 10. SP3 completely replaced Android in my daily use: - Web browsing is just infinitely faster. Using stock IE, didn't even try chrome, I hear it is horrendous in Metro - It is perfectly usable as Ebook reader . I am growing old waiting for Montano to port their reader to Windows 8. In the meantime, reading is split between MS's own PDF Reader app, Calibre (I wish he fully supported Metro, but looks like he's heading in that direction) and another epub reader. Main issue: outside of Calibre, no other epub readers in Windows world are faithful enough in rendering technical epubs - ones with diags, tables, fixed font snippets ( like code in programming books). I end up skinning the tech epubs to my liking (Calibre rules supreme - u basically just edit the CSS!) and converting them to PDF. For usual epub books (novels etc), pretty much anything works. Tablet is light enough to read on, as long as you rest the edge/weight thereof on your spare tire. - For maps/traffic, I simply open maps.google.com in the browser (bookmark your location). Use case: about to travel, what's the traffic like. - Instead of RainyDays, I bookmarked the animated Doppler Gif for my area directly from gov't weather site. Use case: may be going hiking/fishing, is it going to rain in next N hours - For tides, I bookmarked NOAA tide table URL. Going fishing, wanna see tides. - For weather, I bookmarked Google weather page for my zipcode. It gives you hour-by-hour temp, wind. As accurate as the source they use (govt weather), but good enough for today and maaaay be tomorrow. The dedicated weather sites are simply horrendous. If you really wanna know if it is going to rain, open the doppler gif. - I installed the official google search app. Main use: voice search. It is outright scary how accurate the VR is, even wid me accent. - For twitter, nothing beats using their website. The app, Android and Metro, are sheer horror, avoid em like plague - For forums, I installed the Metro Tapatalk. Usable enough, about par with Android, but still has bugs here and there. Of course not all forums support the API that Tapatalk uses and there you have to use web ui. Still I have about 5 forums that I read using tapatalk. - the keyboard is a god send. I even use it as support for the tablet in landscape mode. Fold it back, open the rear latch and now you can have a very sturdy thing in your lap. Very very lapable - After disabling the indexer, the tablet never even gets warm when in use. I dont play games on mine. - Pen and OneNote are pure heaven. Bliss. Nuff said. I do wish they threw more of Word's more advanced features into OneNote. - Stock email client is nice. Use it for Gmail and ActiveSync access to my work email - Stock alarm sees occasional use - More so for stock News reader apps - when I want to read more lies and half truths from our "free" press. Mostly read tech and auto news. Somewhat related. Stock Metro notification interface is a horrendous mess compared to Android. I still hope MS will insentivise top app devs to port their wares to Metro by throwing benjamins at em. But with the new jefe "Cloud" Satya @ MS, we will be lucky to even see SP line continued. HTF chose him to lead MS is totally beyond me.
