I can see the appeal of a smaller more portable unit but to be honest I'm not a fan of the new design or download only content. I'm sure there is a place for this and it will appeal to some for just the same reasons that put me off but much as UMDs can be irritating (horrible grinding loading sound for one) its really a minimal thing - I mean my 360 is way louder afterall!
I don't really fancy being overly reliant on Sony's idea of digital content pricing either (or anyone's for that matter) as I find that often physical versions of games (for the moment) can be purchased for much less online or in the shops. The Xbox live games on demand is a perfect example of this - for instance Assassin's Creed is on there for £19.99 but you can buy the physical game for £9.99 online. £10 extra for the 'convenience' of downloading it straight to my 360? No thanks...
Obviously the pricing has to reflect some sort of reasonable gain for the game companies and also Sony/Microsoft itselfs but when it comes to digital versions of physical games I think the disparity is a bit offputting (for me at least). Obvioulsy with the above example it's a bit different as retailers always discount old stock and follow different pricing models and it IS a different animal to digital distribution but paying more for something digitally doesn't really appeal to me. This is of course different to new games released in digital and physical format as from what I've seen they tend to match more in price. Obviously the PSP Minis will come into play pretty well for this (well if the bad publicity about no multi-player or dlc doesn't kill everyone's enthusiam!) as the concept of bite sized gaming with lower price points is good for everyone. I wouldn't upgrade to a PSPGo just for that though - but I might be tempted to download a few minis to my Slim and Lite if something takes my fancy!
Maybe I'm just old fashioned. I can see the appeal and the benefits, it just doesn't appeal to me
at the moment so I can't really imagine buying one.
Plus I only got my PSP last year so upgrading is the last thing on my mind. I like my shiny silver LE Crisis Core one just fine!
