I've given an iPad 1, Samsung Chromebook & Surface RT a fair amount of time for each being a daily driver. In terms of value, definitely feel like the Surface RT wins in the category. Chromebooks are fine for web browsing, but that's about it - I've had a fair amount of frustration with their "offline" functionality, especially related to Google Drive's Office alternatives. Printing on the Chromebook is difficult unless you are familiar with Google's Cloud Print. I've also noticed a steep decline in battery life over it's lifespan. Combined with a cheap build quality, you get what you pay for. Not saying that it's a horrible machine, but I think it's a passable device for the average user only if they simply want to browse the web. If you want absolutely anything more than that, I'd steer away from those. The iPad 1 still has a spectacular battery and is my entertainment driver as I use it to push Netflix out to a TV. However, even combined with a Bluetooth keyboard I never felt like I could get real work done without going over to a different machine. My browser constantly crashes, but I hope a device with better specs (iPad 2) would age more gracefully.
Relative to the Chromebook, my Surface has provided a pain-free browsing experience. App availability hasn't been an issue (not a gamer, though) as the browser or built-in programs have remedied many of my own needs. Using the split-pane feature is pretty cool, and now I feel like it would be difficult to use a tablet without a USB port of some kind. No issues ever printing, only thing I really miss is the lack of browser add-ons in IE, but some of these problems can be remedied through apps. After being a Surface RT user for a few months, I can honestly say it was surely worth the investment. If you don't mind a smaller screen, I'd echo the comments above about the DV8P - fantastic device with 8.1.
