7. Fan, noise and heat: While the HP is a fanless, quiet and zero-failure design, the Acer has a conventional fan. This is a big selling point for this HP.
8. Charging: Acer has a conventional (proprietary) laptop charger. The HP uses MicroUSB, which you can also use for all non-Apple smartphones and many tablets. Big win for HP.
9. Ports: Acer offers USB 3.0 (instead of 2.0) and a MicroSD slot. It's also possible to physically lock the Acer with one of those laptop chains. I don't think USB 3.0 and a MicroSD slot appeals much to a Chromebook user, but for what it's worth, Acer easily wins this round.
10. Price and value: $250 and $279, respectively. Seriously, who cares? For the price, it's like asking if you want Elvis Presley or Frank Sinatra to perform at your party for next to nothing.The bottom line is this: The biggest single constraint is whether you need the Acer's massively superior CPU power, thanks to the Intel Haswell chip. Some want and need this; others don't. With it, you also get better battery life. If you don't need or appreciate this CPU horsepower, the HP gives you a better display, slightly better keyboard, a silent fanless design that will run cold in your lap, as well as the brilliant idea of using a cell phone charger for the laptop. In my case, I give the edge to the Acer simply because I think I need the additional CPU horsepower as I navigate lots of complex browser tabs. In an ideal world, I would like to combine this one Acer advantage with all the other supremely attractive traits of the HP Chromebook. We will soon see larger (14-inch display, plus or minus) Chromebooks with embedded LTE. Google's assault on Microsoft's and Apple's PC dominance has just gotten started, but the non-reviewers in the peanut gallery aren't seeing it yet. If a PC can't run Photoshop or play some absurd childish game, it can be dismissed, in their view. Acer got a bit burned on the netbook craze in early 2009. It wouldn't jump into the Chromebook world with this aggressive $250 Haswell-based offer if the company wasn't certain Chromebooks were winning against Microsoft and Apple in the marketplace. This $250 Acer Chromebook isn't perfect. The display isn't the very best. It's not fanless, like the HP. It's got a proprietary laptop charger. However, it's got Intel Haswell horsepower, and it's a solid laptop all-around otherwise. For $250, it's a superb value that I highly recommend. Every Chromebook or two sold, realistically, means one fewer Microsoft Windows or Apple laptop sold. Good luck to you if you don't see that.
