There are expansion slots for an SD card, USB flash drives, a MultiMedia card, and more. Bluetooth support is built-in of course. The battery lasts about 2-3 hours depending on screen brightness, Wi-Fi use, and more but there is an optional multi-hour battery if you really want to add some extra weight (about 0.5 lb) and bulk on the back. That may well be worth it if you really want to get cranking on some applications. The system on the HP Mini 1010NR (http://www.laptopspark.com/products/HP-ProBook-4420s-XT987UTABA-NoteBook-Intel-Core-i5-480M266GHz-14-4GB-Memory-DDR3-1066-500GB-HDD-7200rpm-DVD-Super-Multi-Intel-HD-Graphics-laptop-1130.html) will run Microsoft Office 2007 just fine, especially if you opt for additional memory. Open Office will provide even better results for mostusers. The system comes with some pre-installed programs such as Windows XP Home Edition, MS Works, MS Office Home and Student Edition 60-day trial, and a few HP-exclusive add-ons like Recovery Manager and Total Care Advisor. Many netbook (http://www.laptopspark.com) work well with Word and Excel (or Writer/Calc, the Open Office alternatives). But there are some that suffer some serious problems if it comes to Powerpoint (or Impress). The HP Pavilion dv6-3210us NoteBook AMD Phenom II Dual-Core N660(3.0GHz) 15.6" 4GB Memory 500GB HDD 5400rpm DVD Super Multi ATI Radeon HD 4250 (http://www.laptopspark.com/products/HP-Pavilion-dv6-3210us-NoteBook-AMD-Phenom-II-Dual-Core-N66030GHz-156-4GB-Memory-500GB-HDD-5400rpm-DVD-Super-Multi-ATI-Radeon-HD-4250-laptop-1131.html) does just fine with that, giving it an edge in this area, as well. The smaller screen might not be the best platform for creating full-blown graphical presentations especially if you plan to show some cool animations. But for checking the final results on the road or before a meeting, the HP Mini comes in pretty handy. Like the competing models, email and web surfing are no problem at all. Thanks to the wireless support and the Brightview graphics feature, access and readability are outstanding on this little powerhouse. You experience that the keyboard allows you to type normally. You won?t have to relearn any automated skills with this netbook.
