Here's my guesses at the thinking behind the differences from the HDR-T2. Apologies in advance for being a bit tongue in cheek!
Are my recording saved if I reset the Unit = No - why would you selectively reset? Treat as a return to factory settings that fixes everything.
Is there an Edit Channels option = No - Youview stakeholders value and market their LCNs and don't see why a normal consumer would want to deviate from the proscribed plan.
Can we set up Favourites = No - why do you want to restrict yourself to channels when Youview let's you pick from your favourite genres across all channels?
Is there a Manual Tuning option = No - Youview box selects correct region from available signals based on your postcode and then signal strength.
Padding of timers = No padding options - don't you trust the on-time programming signalling?
Manual schedule times = No - don't you trust the on-time programming signalling and advanced EPG?
Edit schedule timers = No - as above
Extend instant Record time = No -as above.
EPG Programme searches = No (on demand only ) - has been mentioned as a future update.
USB File exports = No - why would broadcasters help you make an illegal DRM free second copy of a program?
WiFi Available = Not at present (Future enhansement) - WiFi is a poor substitute for Cable or Powerline anyway. To be discouraged to give more consistent performance to more users.
Can I skip adverts = No - why should Youview stakeholders let you reduce their income from commercials by allowing you to skip them? They don't allow this on PC platforms so why Youview? (technology finally allows them to stop ad skipping and they are damn well oing to use it!).
Can I select multiple recordings to delete = No - but there is now 1 button delete va the remote.
Is there a folders option = No - didn't feature in the focus groups as something people other than geeks would actually use.
Can I record on demand content = No - why the heck would we let you view content past the deadline we have paid our rights holders for the OTT services? They'll blame us for allowing breach of contract and sue us as they then want to sell the content on to other online paid for services....
Power up time = 2 Mins 13 Secs - but MUCH quicker if you turn off Eco mode. Is this comparing apples with apples? Does the HDR-T2 boot quickly from total cold state?
Power Down time = 6 Mins 7 Secs - but instantaneous if you turn off ECo mode
Quick power up = 23 Secs (Requires 16.2 Watt Standby) - Doesn't seem that slow to me.
OTA Software updates = No - but it's an online box. Why would you buy a Youview box without connecting it to the net?
Resolution change options = No - auto senses your TVs capability
Aspect ratio change options = No - why do you want to distort your picture when you can do that on the TV itself? Auto senses your display via HDMI.
Screen Saver = No - has a power save time setting.
Can I use alternate Remote codes = No - urrr yes you can put codes into the remote to use it as your TV remote as well.
Is a CAM slot available = No - BT are moving to broadcast linear channels via IPTV and why should they let you use a TUTV cam anyway?
Do Vision / Connect channels work = No - competitors! They should be on Youview instead....
Can you skip forward / backwards = No - we are not going to annoy our commercial advertisers by deliberately giving you Ad Skipping tools! But you can FF / Rewind PVR recordings.
Is slow motion available = No Geek toy.
FTP Server Available = No Geek toy
DLNA Server / Client Available = No use your smart TV......
