Mine turned up today!
Quick timeline: I received my Steam payment email last Thursday (20th July) and paid Friday 21st July. Item received today, 28th. The Dutch Parcelforce (GLS) site, never updated until today, so don't be too disheartened if it seems to be stuck in limbo! Mine seemed to state it was going to the GLS Final Parcel Centre but never updated.
The first I knew it was out for UK delivery was when the Parcelforce rang my doorbell! This was my fault to be fair, I never checked my emails this morning. You should get an email from Parcelforce confirming a delivery window. Faultless service 6 days. Ordered the day after Steam launched pre-orders last year, Steam are ramping up manufacturing as I was never expecting mine until September.
First impressions, I was really worried I would have immediate buyers remorse, since I bought a Switch and to be honest, its hardly ever been used. Partly because the games cost so much, with the exception of Nintendo exclusives, the majority of games on the Switch that I do like, I own on Steam.
Undoubtedly big but the form factor and weight suit me. The Switch quickly gave me hand cramps, therefore always resorted to table top mode or adding a third party silicon case to pad it out. Driving sim games, the joy cons, shoulder pads work really well with the Deck. The finger tip buttons for ring and middle fingers need to be broken in as they are quite stiff.
Updating, took a moment, and only tried a couple of games so far, Euro Trucker Sim 2 and Race 07. ETS 2 is supported and works brilliantly, only trying to spot which gear you are in - its miniscule, so auto box may be better.
Tried one of all my all time favourite drivers sims which is unsupported, Simbin Race 07. Works brilliantly the only issue I can see, is trying to 'escape' to the main menu? I haven't figured out how you can create a keyboard shortcut to go back to the main game menu? I am not sure if its going to need a keyboard. Graphics, sound and playability, the cars controlled really well, the main menu options are fiddly and take patience as the touch screen will miss menu options, just took perseverance.
Screen wise, I own the 512 which has the anti-glare coating and to be honest, its still glossy and whilst no OLED, I am really happy, its bright and games look good, no major faults I can see.
