Well as the title says, are you happy with your TX2500Z? I'm debating between a Dell XT (refurb) and a TX2500Z so I just want to know what you guys think of your machine. Do you think that it is slow, fast, or just right for any work that you do? How do you find the build quality of the machine? Is it sturdy? Does it feel like it is made of quality material and do you find it heavy? Do you think the machine will last? Approximately how long does the battery last? Does the TX2500Z get hot so hot that you can't bear it? I've read how people feel discomfort but wouldn't a little underclocking fix that? Also how is the fan noise? Thoughts? Is it worth the money? Thanks (Sorry if thats a lot of questions haha, sometimes they just needed to be asked, and sorry if they have been asked already, I have used the search).
