errrmm actually since I bought my 1st device till now (desktop pc, mobile phones and notebooks), I never used every warranty that they give to me... and fortunately I still have my: 10yrs pentium 4 desktop, 8yrs SE W810i, 6yrs SE P1i and Axioo notebook, 2yrs iPhone 3G, 7mths toshiba netbook. all still kicking except for battery life :-D
note: I never broke all devices above :-D thus never use the warranty itself.. so, thats why I begin think that I dont need warranty at all :-D
n then last Nov 2010 I bought my new iPhone 4 without warranty and this week I bought XPS without warranty too :-D
PS.
1. I dont like play games with PC or Lappy coz I prefer XBOX n PS3 >> maybe this is one reason why I never broke my PC or Lappy :-D
2. I never turn on my PC or Lappy 24hours for download or torrenting, coz I already have 30Gb private server that can queue downloads, such as torrent. So, my lappy can sleep too :-D >> 2nd reason :-)
3. I only use my lappy for design, streaming movie, chat, emailing and internet only :-D
thts why I so confident bought this XPS without warranty hehehe :-D
wow, that is very careful use of ya machines...
