I wouldn't, the OG transformer does everything the new Infinity can do. My father and Aunt both have the OG transformer and I find that the Infinity is more comfortable to hold but if I had the OG I'd wait for at least the next generation.
I find the Infinity's battery to be less than stellar, but perhaps my expectations of it are too high. There's also notorious screen/glass separation issues and there's apps that just don't work with the Infinity's higher resolution screen, NBA jam comes to mind and until very recently Draw Something. Dust under the screen is still an issue, I just had a HUGE piece of dust under that gorgeous screen that appeared magically and just as magically disappeared and was pretty pissed about it while it was there, near the hdmi input. The other thing is I find games sometimes crash and I'll have to do a tablet restart to get it to run stuff correctly although this doesn't happen very often and happens less often if I go into developer options and set maximum processes to 4.
Don't get me wrong, I think the TF700 is a huge upgrade over the TF101 and I'm overall pretty happy with it but if you're happy with the TF101 then I'd wait for the next generation because I feel like this thing would run a lot better had it had more ram. I've also not used a TF101 for any length of time where I'd be able to compare battery life but I'd say I usually get around 4-6hours of screen time on with the tablet balanced mode. Games seem to run just fine set to powersavings mode too, for the most part aside from something like Dead Trigger. That also reminds me, You CANNOT use the PS3 controller over bluetooth unless you root your tablet and buy the ps3 controller app from the play store. Unlike the Prime, TF300 and TF101 the Infinity TF700 does not have the driver necessary. So, for what's it's worth, that's another strike against the TF700.
*edit* Also, the headphone jack is in the ABSOLUTE WORST PLACE EVER on the TF700. Lower left side where you'd be holding the tablet. /shrug.
*edit2* Forgot to mention, the screen really is THAT much nicer though. Aside from the resolution difference, colors are vastly more vivid compared to the other Transformers.
