Reply to Change my VCI100SE for an iPad 2?

Opinion please.
I've a VCI100SE (1.4 FW with tasty arcade buttons). The features are fantastic, I like it lots (actually not so keen on the arcade buttons, prefer my Akai LPD8 pads) but I'm considering selling it for an iPad 2 to use as an alternative controller for Traktor.
Am I crazy?

Firstly, it means I can get my paws on a shiny iPad BUT will I be able to use it for proper live DJing (using apps like Touch OSC) and would I miss the VCI?

I plan to move back to using external mode mixing with an analogue mixer so I don't lose the use of real faders and gain/EQ knobs. One of my regular gigs involves me using DVS vinyl setup with the club's house mixer anyway so I've never needed the VCI for anything other than home use and the odd house party but I'll have the mixer. I like the idea of a good touchscreen but with some hands on buttons and tings.

I hope to be able to map TouchOSC to get similar control that the VCI gives (I expect it to be difficult, DJTT's VCI mapping is super tight) and I guess having the iPad would give me more flexibility in the future (ie as new fancy apps arrive)

I've tried TouchOSC with my iPhone but never got round to fathoming the seemingly complicated setup. I want the iPad setup to be as simple as poss and reliable. Ive heard about using a wired USB setup (with apples camera connection kit or using MyWi style apps for wired tethering via the iPad USB cable) but also understand that using it wirelessly via an ad-hoc wifi connection is ok for good latency. Thoughts?

Questions:

- Are there any better altenatives to touch osc bearing in mind I'd prefer to stick with Traktor / any Traktor 'skins' (like Emulator) that can run on an iPad?

- What do people believe of these dedicated apps for running Virtual DJ etc?
I'm not interested in using the iPad on it's own without a laptop for anything other than for fun with DJ apps. I look forward to the day that an iPad can run Traktor (properly) with decent storage etc so right now I want to use is as a midi controller.

- Am I going to potentially run into other problems when playing that I haven't considered?
Am I maybe being seduced by the idea of using a fancy iPad?

Ps I have a windows 7 laptop, Traktro Scratch Pro 1 and an Audio4DJ (and a an analogue mixer plus an Akai LPD8 I could dig out for extra button mashing)
