inspiron 1720 Q's

i am just about to get my 1720 in a week...... i don't know whether i'll be happy with my purchase or not...... well thats what i get for not doing some research......!!

any ways i have some questions...... if some one could help....... preferably from 1720 owners......!!!

1) hows the dual layer DVD writer....... i have heard its got some serious issues in writing DVDs...... and that it could not be read by other drives...... does this pose a real threat......???

2) what abt the display..... is it better than the ones on the 1520...... i am really worried in this dept...... coz i'll be textin a lot....!!!!!

3) have any of u guys experienced heat issues...... i mean does it get too hot when over load......

4) does the headphone jack in the 1720 produce unwanted noise like the 1520......

5) lastly.... what do you guys have to say about the overall performance of the notebook..... r u impressed......?????

sorry for my Q's...... but i am kinda anxious to know......

BTW these where my specs i opted for....
T7500 2.2Ghz
2Gb ram
8600mGT
160 gb 7200rpm
1920*1200 display!!
