One of my biggest gripes these days with buying PC's, is the fact that most come with windows installed, & in saying that, you are paying a premium for windows being on it. try asking the store to give you a discount & not have windows on it. they'll say they can't do that, neither do you get the windows disc anymore. sometimes you do get a windows installer, or a system recovery disc, but it isn't a proper disc, it's more like an image, so when you reinstall, you get all the bloatware crap back. mostly the recovery soft is on a partition on the hard drive. you're buggered if your drive fails (no disc to reinstall onto your new drive)..
yes, most prompt you to make a backup disc when you 1st boot up, but have you seen the amount of time it takes to create that disc? not something you might want to do when you 1st buy the laptop & switch it on to play with, then ultimately you end up forgetting.
i love Linux, i don't play games on my pc/laptop i use it for work only. so really i have no need for windows. but try getting a laptop you like that doesn't come with an o/s installed & did i mention you pay for windows only to never use it (in my case).
then low & behold, because i have reformatted and re-partitioned the drive to install linux & removed the recovery partition cos it takes up space with unwanted software, when something goes wrong the store doesn't want to know because they say effectively that i breached the t&c or something by removing the recovery partition & that they can no longer support it, even though the issue may not be related to the hard drive or software.
though still better than the high premiums you pay for apple products, even though i like the apple aluminium cases & in some ways i like os/x. but not enough to warrant the extra £££ when a linux box is good enough if not better.
my next gripe is definitely with battery life. & in particular the price of a replacement battery that loses it's capacity after a year - 2 yrs..
i also wish that laptop manufacturers would come to an agreement like mobile phone manufacturers did & standardise the mains power supply so that whilst you're at your friends or in the office and you've forgotten your psu, there is most likely someone with a laptop you could possibly borrow to give your poor battery a good charge for an hour or 2 if need be.
