upgrade/controllers will decrease in value, esp with the twitch being brand new. look at the s4 as an example. i waited a few months and saved over $400
True. However, I sold my VCI about 2 months ago with the aim of getting the Twitch as a replacement as I love the look of it.
However, I use my studio PC for production and gaming. The new setup is likely to be Core i5 2600k overclocked to 4.4GHz, 16GB DDR3 RAM, 2 x 500GB hard drives (Windows 7 installed on one and MAC OSX Lion on the other), a 1TB file storage drive for music files etc and 2 x ATi Radeon 6870 graphics card set up as Crossfire.
I have a lot of the above components already hence why both will come within budget.
And that PC upgrade will piss all over, or at least go toe.to toe, with any iMac at a fraction of the price (before anyone else turns it into a PC v Mac debate).
