If you haven't already purchased your choice, do NOT buy a HP laptop. I had an X2 envy (hybrid laptop/tablet), but after sales help is non-existent. I would constantly, but randomly, get a BSOD referring to the same fault, and HP never replied to any of the reports submitted. How do I know? People who still have the X2 envy are still getting the BSOD indicating the same problem. The best decision I ever made was to get rid of it!
Back to your question. What you buy is what you think is best for you at time of purchase. You won't buy a desktop pc off the shelf with futures needs in mind, so you'll have to get one custom built. I did, and it was still ahead of it's time for 18 months, then technology caught up and I was left to struggle in it's wake. I then went the 9android powered) Pendo route, but found it to be severely wanting. I then went with the X2 as, at the time of purchase, it was the only tablet that would run a external portable HDD. I dealt with the constant BSOD, but it soon became a PITA. Since I got the S3, all I have had a problem with is the random lock-up. It freezes everything, and to solve it you have to turn it off and reboot it. Because of that, I now save any document after each line, or entry. It can be a PITA, but at least it is better than losing an hour's work.
