So today I went to my local Game store to test out the Playstation Vita, and I have to say I loved it. I played on Wipeout. The screen blew me away on that thing! But, I loved it so much I put in a pre-order for my own Vita, which will go happily side by side with my 3DS.
I will be doing a comparison between 3DS and Vita mark II once I have the Vita, so watch this space! Currently getting my Vita with an 8GB memory card, and Rayman, but will probably buy Wipeout, Uncharted, Escape Plan and Super Stardust not long into it's life.
