At AT&T and Verizon, the HTC 8X costs $550 for the 16GB model, while the Lumia 800 series costs $400; a two-year contract drops $350 from those prices. At T-Mobile, the list prices are $50 more, but the discount for a two-year contract also increases by $50. Of the two models I tested, the HTC 8X is the more appealing smartphone. You might consider the $450 Nokia Lumia 920 instead; it has beefier hardware as well as Nokia's special apps, but it's also both larger and heavier than the 8X and Lumia 800 series.
Business connectivity: Decent email, mixed calendar, good contacts, poor office productivityWindows Phone 8 is the first version of Windows Phone that a corporation could seriously consider adopting, thanks to its support of basic EAS policies. The good news is that for basic information worker usage, Windows Phone 8 is adequate, even if less capable in total than what iOS and Android offer.
The Outlook email app supports Exchange, IMAP, and POP accounts, with quick setup options for Gmail and Hotmail. I like Windows Phone's way of handling message groups such as unread and flagged messages: Just swipe to the right to see lists of unread messages; repeat to see flagged messages. It also implements a color highlight on the subject of unread messages in the All message list, but the Unread list is simpler. To save on cellular data usage, attachments don't auto-download, though you can specify that they do when connected to Wi-Fi. Windows Phone 8 can open Zipped attachments (like Android but unlike iOS).
If you have multiple email accounts, Windows Phone 8 grows hinky. You either have to link them (select Linked Inboxes in the More menu; that's the ... menu) so that their inboxes appear merged in the Outlook app, or you have to switch to folder view (via the More menu) to see each account's inbox and folders, then tap the one you want. It's inefficient and far more complicated than how iOS and Android do it.
Outlook's capabilities for working with emails match those in iOS and Android. But the way the options are presented is confusing. Some options are available as icons, while others are available as textual menus via the More menu. Essentially, the ones Microsoft think you will use commonly are available as buttons, but the rest require access through a menu. That's similar to how Android has long worked, but the most recent version of Android has adopted iOS's easier approach: Put all pertinent controls in front of you, rather than force you down menu paths.
