If you want something faster, go for it. If you don't really care and don't need anything faster, AND you like to tinker and/or squeeze every drop of life you can out of things, then don't go for faster. To clarify: This tx2 WILL overheat and cut itself off if I use it nonstop for a few hours. If I just use word processing or email, then dont touch it, it will stay on for days. Also, if I take the battery out, it doesn't overheat, it has more holes for air to get through. also, i didn't deny the fact that things slow down, I'm sure my Tx2 was faster when new, but i've had it shut itself off 3 times in one day with the battery in. It only shuts off when I use it to watch multiple videos for hours on end with it sitting on a blanket, carpet, or similarly nonventilation friendly material. The cooling pad i have is broken, which means it helps keep it on a little longer, but a blanket still somehow just collects the heat and decreases airflow, unlike a flat table or desk. Sure, it's slowed down, sure it's at a point where it's picky about where I put it(but this thing was poorly designed to begin with, and some people have had theirs stop working completely due to the overheating by design problems it has) I'm just saying.. If you are broke, with no job, or perhaps very young and your funds are limited, or maybe even if you want to stretch everything out to its complete limits, swapping out a few things and cleaning goes a long way. As far as the overheated diodes, sure bored I understand components can be damaged by heat, I worked on electronics in the navy, but I personally(opinion here) would still say screw it and force life out of something even if it's damaged. And mainly because I'm poor, but also because I like taking things that people give up on and squeezing more life out of them.
Remember, I was just offering my opinion, and we all have opinions. I personally don't need anything fast, and if I do, I'll use my desktop. I dislike tablets and smartphones, and only like the touchscreen of my laptop for quicker mouse functions like tapping on a link or the x in the corner of the screen without fumbling on a touchpad.
If you're broke like me, and don't have a job like me, it's easier to take some spare parts or a screw driver and some air, and get things to keep going. even if it's not easier, if you like to tinker with things, it's more fun.
99.9% of everything you hear, read, or see is purely opinion and bias. I'd go so far to say that 100% of what you hear or read from others is hearsay. Hearsay is not fact. Opinion is not fact. Evidence is not fact, it's only something that supports the hearsay or opinion. Proof is what is truly lacking, and proof is evidence made into fact. It's a lot harder than people think to establish proof. A lot of times when someone says "I have proof" it's merely evidence, and when people agree that a thing has been proven, it's still just them forming an opinion on some evidence and hearsay, and nothing was truly proven. Just food for thought. Proof is hard and almost impossible, in most circumstances, to establish. The truth varies from person to person. The best place to be is in the middle looking at everyone on both sides as both right and wrong. I admit I mess up and stand on one side of the fence, but everyone else does it and most people don't even feel bad about it. I feel horrible every time I do. Opinions and hearsay are not facts. and evidence is just that, evidence... not proof. That's why theories are still theories(think relativity or evolution), evidence can not prove they are truth.
