I'm new to tablets/notebooks in general... maybe I am missing something, but it doesn't seem like I would have much use for a laptop expansion slot (PCMCIA or ExpressCard). I mean, other than a wireless broadband card (I won't be subscribing to such an expensive service in the near future anyway), what can you do with this thing that you can't do easier/cheaper with some other I/O method? What I am getting at is, the T4210 is without the newer ExpressCard option... and I'm assuming the PCMCIA is going to fade out relatively fast. Should I worry about this for any reason? What do you guys/gals use these expansion slots for anyway? I mean, the T4210 has integrated wireless a/b/g and bluetooth (which I'm assuming means they are actually built-on, not expansion cards), so what will I be using it for?
