Just to correct you:

They're not in English. - Yes they are in English

Don't have support (?) or warranty. - Depends who you buy them from

Poor quality, have a much higher chance of breaking within a few days.
Or just not work at all. - Again depends who you buy them from

Don't look that great, especially the UI. - Depends on your firmware, but seeing how they'll probably spend 90% of the time being in your pocket or bag, what the UI looks doesn't really bother most people (or atleast me)

Have problems with being "hacked." - Depends who you buy them from and remembering that there really isn't anything larger than 2GB will help you avoid this

Having to go throught the trouble of theming and messing with the firmware. - Well thats upto the user and usually the users fault that the player dies when they alter/change the firmware, this is not a problem with the player.

Poor battery life. - Again depends on who and what brand you buy, but you can now buy ones with removable rechargeable battery's.

Sound? - I think its pretty good.

Some don't even have 3.5mm earphone jack (who thought of that?). - Well when the width of the player is less than the diameter of a 3.5 jack, you kind of have to use a 2.5mm jack...but you can always pay a few dollars and get a audio adapter allowing you to use 3.5mm headphones on a 2.5mm jack (without audio quality loss)

Not coming the correct cables (ebay?). - Well thats the sellers fault, nothing to do with the player

Dealing with Ebay sellers. - Don't buy from eBay?????

And other problems I don't have in mind right now.

With all the purchases and dealing with hacked, faulty players and wasting time, couldn't you have gotten a brand name or well-known player for the around the same price. - Well most of your comments have little to do with the player and more to do with the sellers and i don't think you can get a well known player for almost the same price.
