played with one at best buy, trying to use it as a tablet is still too heavy and big
Did you use it as a tablet without the keyboard attached? It weighs in at 800 grams or the same as an iPad with a case. I was very skeptical of the tablet experience, coming from iPads which just
work (otherwise I'm Android and Windows for all my other machines and devices), but the size and aspect ratio won me over when reading comic books and page-sized PDFs... absolutely love that. Less a fan for video and web media consumption because it gets hot and the fan kicks in which is unpleasant in a tablet.
Now if you're talking about an iPad Air, the weight difference is appreciable... but then so is the cost / value proposition / screen size (12" to 9.7" for reading is big, for surfing less so, which is why 7" is so popular).
I do a LOT of travel on trains and international flights so is the new Type Cover going to cut it?
If you're used to mobile / compact keyboards, you'll be fine... and probably feel this type cover is cut above any other tablet cover and on par with most laptops. For all intents and purposes, it is a laptop keyboard... the keys are mechanical with travel and backlit, the touch pad is glass with mechanical clicking, and the whole thing is built out of metal. The only thing that might weird you out is how it doesn't have to lay flat... which can introduce a very little bit of flex... if it bugs you, just lay the keyboard flat!
I'm also on the fence about what size to get; I'm assuming most here have the 256/8GB model? Seems like that with my onedrive account should be fine.
Mine was provided by work, didn't have a choice, but that's what we got and it seems more than adequate so far, particularly with the MicroSD slot. It's probably only me, but I'm slightly uncomfortable at how easily accessible the SD card is. It's probably just a psychological issue... if they can get to your machine and under its kickstand, they can away with the whole thing rather than just stealing your precious data... but SD cards being under a case or latch, etc. somehow feel more secure to me.
Battery life good? I'm hoping for at least 6-7 hours of use doing web/office/visio etc. on it. Not planning to game on it other than perhaps Team Fortress 2.
Battery life has been great so far. On standby, without being touched or charged for nearly five days, it only lost two percent (which couldn't be said of the Pro 2), through regular use I've gotten 7 hours without charging (a workday + lunch having forgotten to bring the charger in). I haven't done endurance testing beyond that. I don't game so I can't speak to that, sorry.
I have heard repeated complaints about people who try to use the SP3 to do podcasts, so if that's your thing you may want to try before your buy and/or hold onto that receipt.
