I recommend Tales from Space, if you haven't played it already. That game also uses the touch controls well, and motion occasionally.

Good for 3DS I say :). I only care about what games I can play on a system, not whether they were made specifically for it or not. But I do get your point, and the vita must expand it´s own library far more than it is now.

No, but give me one game/month instead and let me keep it forever. There is a special thing about actually owning your games, even if they are digital. I am equally as critical towards MS for releasing some really old games for free to their subscribers.

it can also be that I am so used to XBL that I do not give PS store a fair chance. I just feel that it lacks a clean overview and well thought-out design to really be as good at it can be.

You could be right about the downloads but they are equally big, don´t known why that is. Also, the system refuses to download Big Planet for some reason :(.

You're obviously being Xbox biased here, which is understandable coming from an Xbox past. 

Yes, you can keep your free live games forever. But, think about it. Do you go back to these games and replay them? Some games have a lot of replayability, mostly multiplayer games, but for the story driven ones, I seriously doubt you would go back and replay over and over again the same story. With plus, I get 10x the amount of free games as Xbox, most of them newer and more expensive experiences, and get a year to beat them as much as I want. I still have the game, but can only play with the subscription. 

Long story short: I'm going to beat Bioshock 2 or Hitman Absolution for the 3rd and 4th time a year from now.

What a lovely attitude :)

Glad to hear you're enjoying your new system.  I love mine.  I could recommend you hundreds of games but I'll keep it as short and concise as I can for now:

Vita retail games: Gravity Rush; LittleBigPlanet & WipEout 2048 are my favourites.  Need for Speed: Most Wanted & Dead or Alive 5+ are good console ports.

Vita downloadable games: Hotline Miami & Guacamelee are essential; both on sale in Europe at the minute.  Super Stardust Delta is sublime.

PSP compatible games: Ys Oath in Felghana; Daxter & WipEout Pulse are among my favourites.  GTA: Vice City Stories is great to have on the go.  Metal Gear Solid: Peace Walker is great if you're into the series.

PS1 compatible games: I love having the Spyro & Crash series on the go with me at all times.  Ridge Racer Type 4 is great.  Metal Gear Solid 1 is still excellent.

The PS3 store and the PSVita store are different. You have to compare the PSVita store to the 3DS one, wich is considerably slower.

PS store on the PS3 is not as fast as the Xbox one, but its alot better looking in my opinion.

As far as your downloads go, that is weird. Maybe you clicked the download button twice? Its very weird, i didnt get that at all.

Well, for example I have played through Halo 3 3 times now, and Gears of War 4 times so I revisit alot of games that are of high quality. I have never rented games at all, I prefer to own what I game. I am XBox biased, but that doesn´t relly make my point any less valid, does it? If I feel they offer a better solution, that is just my opinion just as it is your opinion that it is a better solution with PS+.
