probably wait for the nokia lumia 630.. a bit newer than the 625.
pros...
1. has the latest windows phone 8.1
2. has dual-sim model (2G & 3G)
3. unlike the also latest lumia 930 (icon), the 630 has replaceable back cover, battery, & memory card expansion
cons...
1. windows phone apps ecosystem is still growing
2. screen display resolution is not top-of-the line, well kasi naman, the 630 is an affordable variant
i'm not a fan of a lot of apps, i just want those that are enough & functions well.
check those windows phone apps before you use a windows smartphone, then decide if it is for you.
it all boils down to what you want to experience... the apple, android or windows experience.
BR & God bless
