Re: There is NO tablet ... that can come close to competing with my high-end laptop

You struggle to buy anything "underpowered" these days. The bottom-end laptop these days is comparable to a mid-range laptop when W7 came out. Since W7 doesn't need more resources now than it did then, a cheap laptop is quite adequate these days.
We've finally escaped the days when business laptops had the Intel 940 graphics chipset, now even cheap laptops with integrated GPUs support DX10 properly... I work developing 3D software for business clients so this is something I am sadly rather well acquainted with :) Low-end tech these days is not only powerful, but far more consistent than it was even 5 years ago.
