[citation][nom]gm0n3y[/nom]While I understand that most people aren't going to want to open it, I think that it is still a negative point. I would like to be able to upgrade the SSD (for example) if I feel like it. And who wants to pay an extra $150 for a warranty? I'd rather just be able to replace the screen myself if I break it.[/citation]
If you think you are likely to break the screen within 2 years, it's far cheaper and less hassle to pay for the warranty. The digitizer/screen is a lot more than the cost of the warranty. That being said, a design where you can pop a piece of the back cover off, swap out the SSD with just a few screws would be nice, but tablet makers will never do that for the simple reason that they want to up-sell you on an overpriced upgrade when you buy the device.
And not to say anything bad about you, or your repair skills, but the screen is in fact replaceable. If the trade off for *you* being able to replace the screen is that everyone either has a thicker, less durable tablet, or it's a lot more expensive, I vote for you getting inconvenienced for something you would like to be able to do, but are never actually going to do anyway.
In either case, it's clearly a question of priorities. If upgrading and repairing your own device are so damned important, buy an ultrabook. Same specs, likely more user-serviceable. If a tightly integrated, smaller/lighter device is more important, get a tablet.
This debate reminds me of all the older mechanics complaining about fuel injection. They will stick with a carb they constantly have to fiddle with, with less mpg, less power, and worse emissions, just for the sake of not needing a code scanner to see exactly what's wrong. The old excuse being, it's too difficult for the home mechanic to work on or fix, when the truth is, given enough time, tools optimized to do the job in question will become cheap and general understanding of FI will increase to the point of making carbs look like stone-age tech.
My point is: Eventually, kids will just make fun of you for using a laptop (because you think it's easier to work on).
