I'm thinking of buying a used beaten 5112 while I wait for something that will be better and cheap enough to be worth buying, are they reasonably decent machines? I was hoping for something smaller and lighter but I just can't see paying more than $500 for less than netbook performance and the Android devices do not have some of the things I want like a real office suite, ability to connect RS232 devices, etc. Is it easy to get inside the 5112 to replace the hard drive? I'm pretty sure that newer drives are faster and use less energy, I might also go with an SSD to again reduce heat and energy consumption (if I can get one cheap enough). If you see the recurring theme of cheap, I don't want to spend too much money on this because I now there will be good device coming and I don't want too much money to be a waste when those better device arrive. The Q550 was close but way too much money, if it was under $500 I would have probably bought it already. Also if I buy one, would anyone that has a 5112 be kind enough to copy the restore disk? None of the ebay devices come with disks and while a plain install is normally better, it is nice to have the restore disk available if something doesn't work correctly.
