New purchases planned this year: 2 iPhone 5 1 iPad 2 1 AirPort Extreme base station 1 2TB External For gigabit network of 2 Macs (G5 Tiger + iMac Snow Leopard), 1 PC (Windows XP) and 6 printers. Obviously, iPhone 5 has not yet been released. I was hoping to hold out for a true 4G but my current iPhone is aging badly (buzzing, no wifi, dead pixels, slow). My current AE base station does not support 802.11n. Don't want this to be a bottleneck for iPhone and iPad wifi. The AE guest feature is also nice. However, theres a $320 premium for the built-in 2TB version. External 2TB drives are going for around $90-150. So I plan to get the standard AE base station. Questions: Will I achieve maximum wireless speed on my network? Sometimes wifi is necessary to control iTunes via iPhone Remote app. Which external 2TB drive is recommended for network backups (via CCC)? Based on number of votes on NewEgg, Western Digital Elements 2TB USB 2.0 Desktop External Hard Drive WDBAAU0020HBK-NESN seems to be top pick.
