However, it would be better for the screen size if it went more in the direction of the rigol UI.
There you have almost everything relevant at a glance.
It will be better in terms of features and technical data, it just depends on the price that siglent wants for it.

Just some notes.

SDS800X HD have same UI as SDS1000X HD, touch and mouse. Exception is display physical dimensions.
(also much same as in SDS2000X HD)

And example very superior BodePlot.

4 math channels with formula editor. Math channels can cascade.
(Filter, +, -, x, ÷, ∫dt, d/dt, √, Identity, Negation, |x|, Sign, ex, 10x, ln, lg,
Interpolation, Max hold, Min hold, ERES, Average, Formula Editor
2M FFT)

Always in normal mode background working acquisition history buffer.

Also (optional) comprehensive Power Analysis. 

200MHz BW SDS824X HD
2GSa/s  for 1 channel  // 100M memory
1GSa/s  for 2 channels  // 2 x 50M
500MSa/s for 3 and 4 channel // 3 or 4 x 25M
Full resolution 500uV/div (Rigol have 1mV/div full resolution)

Always available true dots mode. Displayed interpolation is post processed so also after stop it can switch for display true sample dots or change displayed interpolation for x or Sinc (including also history buffer independent if it is captured in normal mode or fast sequence mode.). 
Naturally also math channels can cascade.

Analog front end channels offset ranges:

Siglent SDS800X HD all models
±1.6 V:  500 μV/div ~ 5 mV/div (including also <500 μV/div vertical zoom)
±4 V:    5.1 mV/div - 10 mV/div
±8 V:   10.2 mV/div - 100 mV/div
±80 V:  102 mV/div  - 1V/div
±400 V: 1.02 V/div  - 10 V/div

Rigol DHO814
±0.5 V: <500 μV/div
±1 V:   ≥500 μV/div - 65 mV/div
±8 V:    >65 mV/div - 270 mV/div
±20 V:  >270 mV/div - 2.75 V/div
±100 V: >2.75 V/div - 10 V/div

I forgot to mention the screen. It's really, REALLY readable compared to last-gen 'scopes. The font rendering, etc., is that good.

Some appreciate beautiful pictures, others appreciate measurements quality.

--- End quote ---

Why would it lose warranty?

You don't have to open the case and the hack is completely reversible.

If the 'scope is dead they'll never know you hacked it.

If it isn't dead you can change it back to a DHO804 before you send it in.

As a manufacturer you want to investigate why it is dead and returned for warranty. So you can catch issues early on. When they find a corrupted SD card / vendor.bin file, there is a (albeit small) chance they will deny your warranty claim as overwriting vendor.bin file(s) is outside the normal intended use for the scope, just as deep sea diving with it, is.

If that happens at all (which is very unlikely) then it will be a way down the chain, a long after it was replaced by customer support. Customer support doesn't have time to forensically analyze every case before responding)

That's if they even care or bother to check that when it's the power section that failed.

nb. You can also hack it by generating license keys. That's not a unintended use.

There are a lot of "ifs" here, but it's not so clear cut.
Such as with "warranty void" stickers, the manufacturer cannot outright deny a warranty claim, not legally at least.

If you have modified the software to make the hardware work as it was intended, (the usual meaning of hacking here), it is up to them to prove the link between the hack and the failure, if it is indeed hardware related.
A valid license key generated outside of the regular supply chain cannot make a DHO800 work outside of its design boundaries. Of course, if they denied the claim, it would be a really expensive endeavor to hire a lawyer and make them honor the warranty. It would give them very bad press in any case.

This is true in the EU, and for private customers, as consumer protection laws don't allow "warranty contracts" to undermine legal rights granted by consumer laws, and they can only improve on them. So, with the third year's warranty, it could still pose a problem.
