<p>Here are some of my thought2:</p>
<p>1). If you want durability, look into the business line of laptops. They might be as flashy or as multimedia feature packed, but they are durable and (usually) come with better customer service. Having dealt with 5-6 HP consumer laptops in the past 4 years, I can say that their quality is mediocre at best. </p>
<p>2). $1400 is plenty to get all of the features you are looking for. One thing to note is that RAM and harddrive are both easily replaceable and upgradeable. Processor and graphics, on the other hand, are not. So if you have to decide between upgrading one or the other, go with higher specs for the non-upgradeable components (particularly if you want to keep that laptop for a long time). </p>
<p>3). If you are using this laptop as a primary computer and you want to use it as a somewhat powerful entertainment machine, then a tablet is not a good choice. Not only is the screen small (I wouldn't want to watch HD on a 12 inch screen), keyboard cramped, and graphics integrated (ATI), but you can't even get blu-ray as an option. Not to mention tablets are generally more expensive (more likely to put you over budget) and engineers generally don't absolutely need a tablet (there is a recent thread on this forum about this). </p>
<p>4). In terms of screen size, yes, I definitely think there is a noticeable difference between 14.1in and 15.4in. My friend has a 14.1in HP, I have a 15.4in HP, and my roommate has a 17in HP. Even though the resolutions for 14.1 and 15.4 are the same, I definitely think my friend's laptop is smaller than mine when I look at the screen. I can tell you for an engineer, screen real estate is pretty important, however if you wish to tote your laptop around, 14.1in might be a better choice. As for 17in, if you are going to carry it around a lot, then you are probably going to want something smaller and lighter. 7-8 lbs of extra weight is no small burden, especially if you are out and about for long periods of time. My roommate never moves his laptop, ever except to go home for extended breaks. I myself don't even carry my 15.4in HP, I use a 12in Lenovo X61 for toting around. </p>
<p>5). Suggestions: </p>
<ul>
<li>I don't know how set your budget is, but you can also look into buying a slightly cheaper primary laptop for around $1200 and then spending $300-400 or so on a netbook for toting around. For example, I was able to customize an HP dv5t with 2.26Ghz processor, 3GB of RAM, 250GB HDD, blu-ray, HD display, and graphics card for about $1200. You might even be able to find decent netbooks for $200 right now.</li>
