content: Looking for advice on a good, inexpensive android tablet. Hey all, title says it all.  I'd like to pick up a decent, yet cheaper android tablet for emails and web surfing.      I kinda consider these things as disposable(they break, people steal them, they quickly get obsolete, etc..) so I don't want to spend a bunch of cash on it ,but don't want a $40 Chinese knock off either. There are so many on ebay and amazon and I have no idea what ones are good or not and don't trust reviews there any longer.   specs:  somethng fast-ish, something in the 8-10 inch category with maybe access to the google store, some kind of external SD slot  type thing for storageand the ability to hook up one of those mobile keyboards.... Any suggestions?
