TF-20 CPU changed to TL-60 dual core 2.0 GHz, installed 4gb ram, works very very good.
win7 64bit works just fine, all the applications are working without any problems.
Video is weak, but is enough to do some 3D processing.
I've bought this machine pre-owned, 100$, plus CPU 30$, plus 2gb ram 40$,
170$ in total for very competitive machine is quite good.
