i was curius. do some tablets have parts that can be replaced? like memory and the HDD?
I would think not. Most tablets are very 'awkwardly' engineered so parts can all fit into that small frame. Design-conscious companies are making their tablets sealed to avoid any ugly screws or anything that might ruin the seamless look.
There is no hard drive in a tablet, I believe its all flash-based memory, because hard drives are sensitive. Tablets are chucked in bags and rotated violently, they'd break instantly. Ignoring that, hard drives are too bulky to begin with.
Even if a company did allow for the swapping of memory (not sure how that'd work since I doubt it uses any memory standard we are used to) I can't imagine your every day user (their target) bothering to do that.
