Maybe...but.
Surface 2 comes with a much better screen, comes with 2 years of 200 gb cloud storage and a year of free Skype. Also, aren't the cameras on the RT2 better as well? Build quality of the hardware?
The build differences are pretty significant. The Surface 2 has a magnesium case that doesn't pick up fingerprints, while the T100 is clear, glossy, flexible plastic that gets greasy incredibly quickly and is hard to clean.
The display on the Surface is also laminated, 50% brighter, 1920x1080 vs. 1366x768, and the colour accuracy is far better:
Surface has 3.5MP front and 5MP back and the T100 has only a 1.2MP front.
I know it sounds like I'm trying to look for an excuse to buy the Surface, which is kinda true. I'm just not sure whether the higher price matches the improvements you get.
Strata8...why not just keep the DM1. If it's the one I just looked up on ebay it looks like a nice device.
It's not, unfortunately. The build quality is one of the worst I've ever seen (hairline cracks along the side of the case and screen stops working randomly), it takes ages to come out of standby, the performance is rubbish due to the HDD, the display is terrible, and it only lasts 4 1/2 hours on a charge. I bought it because it was $280 and it's worked okay for what I use it for so far.
I've got a 2012 Nexus 7 as well which needs to be replaced because it's a bit too slow for my liking. But it's going to cost $824 to replace both of them with newer models ($339 + $485) and that's with the 32GB Nexus 7 and a laptop that's still bound to be pretty bad. I'm getting so much more bang for my buck with a hybrid like the Surface or T100.
