Better top up a bit if want Asus...
Asus A42Je, i3 370M + ATi HD5470, freeDOS@RM1999
else
Samsung R440E, i3-350M + ATi HD545v@RM1899...

or back into budget..
Fujitsu LH520, AMD P320 + ATi HD5430, freeDos@RM1499
Lenovo G465, AMD P340 + ATi HD4270, freeDOS@RM1449
Toshiba C640D-1004U, AMD P320 + ATi HD4250, freeDOS@RM1449
Acer 4551, Athlon II P320 + ATi HD4250, FreeDOS@RM1499

The main problem is "little" games...
Better upgrade/fix your PC for now and later get a laptop....

Pretty much Acer 4820TG and Lenovo Y460...

Better take SXPS 16 but upgrade the GPU to HD5730...

Better screen, higher resolution....
Do note that the SXPS 16 white colour is only the lid colour, not whole body..

Nope, Dell sell at that price...

ATi HD5470 is slightly better...
That Inspiron 14R only using Intel HD, which is much weaker than ATi HD5470/310M, but if you are using with no gaming, then its no problem...
For Toshiba, if you don't mind Intel HD
Toshiba Satellite L645-1006U, i3 350M + Intel HD, FreeDOS@RM2099
if want with dedicated GPU,
Toshiba L645-1112X, i3 370M + ATi HD5470@RM2349...

No beats.

Its mainly if you need the lightness of Vaio Z or not, else HP Envy 14 would be better, if its with the 1600x900 Radiance display.

MBP 13 would the lowest in term of gaming, but wins in battery life...

Well, you said after change to Win 7, then it didn't occur anymore.
Means its software problem...

Its a mix aluminum with magnesium-alloy chassis, but still not built-like MBP...
haven't seen anyone said it corrode....

Light, no other choice than Vaio Z

Quality wise or if you mean durabilty definitely would go with rugged notebook, but then it would not be thin and light...

Slot load could only bring problems later, once the disc stuck, you need to open the notebook just to get the disc out...

and since you mentioned its not slot load, means you are getting the SSD version, which means by default it would give "faster" feeling than the other two....
Games performance wise, the HP Envy 14 and Vaio Z wouldn't differ much, both comes with high resolution with somewhat similar power GPU (HP Envy 14's ATi HD5650 is underclocked, which brings its performance similar with GT330M, else, HD5650 > GT330M )..

15'' closest is
Dell Inspiron 15R, i3 370M + ATi HD550v@RM2499

14''
Dell Inspiron 14R, i3 370M + ATi HD550v@RM2299

HD550v > HD5470, so depends you want better GPU or better CPU

HD5650 is better...

Something within 11.6''? none...
